The terms landwehr ("land defence"), landgraben ("land ditch") and landhege ("land enclosure") refer to border demarcations or border defences and enclosures in Central Europe that were either built by settlements with the right of enclosure or to mark and defend entire territories. These measures, usually comprising earthworks or dykes as well as ditches and impenetrable lines of hedging, for protecting towns and villages date mainly to the High and Late Middle Ages and consist, in some cases, of systems over a hundred kilometres long. Comparable earthworks have been recorded since Antiquity.[1] The Roman limes are the best known examples of earlier landwehrs. The Danewerk is another example of this type of barrier.
Many of these landwehrs have survived, especially in woods and forests, and are often protected as heritage sites.
Purpose
The construction of a landwehr was an effective way of protecting the population of a settlement or territory against attacks by neighbours or enemies in feuds or war, and also to mark out the legal limits of an area. The landwehrs were a means of limiting the likelihood, success, effectiveness, and consequences of medieval warfare, and thus preventing them. They also hindered bands of robbers entering the area and hampered their retreat after a raid. The combination of fencing and thorn bushes was also useful in enclosing cattle pasture and as a guideline in wolf hunting. Wolf pits are often found along the line of a landwehr.
Landwehrs were also used to on a large-scale to enclose woods and agricultural areas for the protection of the local population, where they were settled in dispersed dwellings and farmsteads within the protected area. The landwehr offered protection for the peasantry, in a way analogous to the population of fortified towns who were guarded by a town wall. Often too, the fields and outlying areas surrounding many towns had a ring-shaped enclosure, a so-called Stadtlandwehr ("town Landwehr"), Stadthagen or Stadthege ("town enclosure"). An example of this is the Westphalian city of Dortmund, which, in addition to the city wall, also had a large landwehr surrounding it.[2] As a map of 1748 portrays, Dortmund's Stone Tower was part of this landwehr ring.
The only gaps in landwehr defences were on roads entering the area where, like the gates in a town wall, people and goods were checked as they passed through. For example, landwehrs often acted as effective customs posts, usually imposing a road toll.
Trade routes, particularly in the area of check points, were accompanied on both sides by landwehrs. In addition to protecting travellers from ambushes, these landwehrs on either side of the route were mainly used to channel the flow of traffic and effectively prevent people bypassing or avoiding check points and customs posts.
History
Pre- and early history
Hedges are one of the most natural forms of boundary defence and enclosure. Their simplest and, even today, most common use is as a garden hedge. Even in prehistoric and early historic times, people built defensive enclosures using branches and brambles for the protection of storage places (including caves), fortified residences, houses, estates and settlements from attack by predators or enemies. This is common even today amongst nomadic tribes. Julius Caesar tells e.g. of thick Hagen which were laid out by the Nervii, one of the most powerful Belgic tribes:
Having no strength in cavalry (for even to this day they care naught for that service, but all their power lies in the strength of their infantry), the easier to hamper the cavalry of their neighbours, whenever these made a raid on them, they cut into young saplings and bent them over, and thus by the thick horizontal growth of boughs, and by intertwining with them brambles and thorns, they contrived that these wall-like hedges should serve them as fortifications which not only could not be penetrated, but not even seen through.
A more complicated form of defence was the classic ditch and rampart system. In A.D. 16, Tacitus reported a border fortification built by the Angrivarii, the Angrivarian Wall, which was erected to defend them against the Cherusci. A great battle was fought there in 16 AD. The most important border fortifications were said to have been at Rehburg-Loccum.
The Anglo-Saxon Chronicle speaks of a Bebbanburg around A.D. 547, which was "first fortified by a hedge". The capitularies of Charlemagne also mention "ramparts planted with hedges".
As a rule, mediaeval landwehrs consist of one or more impenetrable lines of hedging made of pleachedhornbeam – (the Gebück) - underplanted with thorny bushes such as blackthorn, hawthorn, dog rose, brambles or holly – (the Gedörn).
In addition there was also usually a combination of one or more of the following elements:
One or more parallel earthen ramparts between or on which the hedge was planted
A path for the maintenance of the hedge and for patrolling the landwehr
Ditches in front, between and behind the ramparts, which were sometimes filled with water, depending on the location e.g. in a valley. As a rule, the ramparts were made from the excavation of the ditches.
Watchtowers, schanzen, abatis and haspels at the checkpoints where roads passed through the landwehr
A "wet border" created by flooding and water ditches
From the time after the Frankish colonisation of Central Europe until the late Late Middle Ages, the creation of fixed sovereign territories ruled by lords and princes led to the establishment of territorial landwehrs which enclosed the land which was legally held by states and settlements. The territories of Gaue, counties (Zenten), regional magistracies (often coterminous with church parishes), Ämter and even entire states were enclosed by landwehrs in the form of defensive hedges.
There were also Landhagen and Stadthagen, which were arranged in a circular shape around smaller settlements. The Landhegen bordered and protected entire regions as well as the areas surrounding towns and cities, for example the almost 70-kilometre-long Aachen Landgraben the former Aachener Reich, similar to the ones in Frankfurt, Rothenburg, Lübeck or Mühlhausen. The traces of the Rothenburg Landhege are still about 60km long today, the Mühlhäusen Landgraben, still some 26km long, recalls the border between Mühlhausen and Eichsfeld.
These earthworks served several functions. They marked, protected and helped to bring peace to territories that were under their reeve (Greve), count (Graf) or Amtmann. This grouping of tasks for the protection of defended territories (Landwehr) resonated with the term Hege (a range of measures concerning hunting and wildlife) in terms such as Hege, Heege, Hag, Haag or Hecke, but also with the term Schutzhecke or "protective hedge". Numerous toponyms such as Zarge, Gebück, Wehrholz or Gehag recall different variants of these defensive structures as e.g. hedges, excavation works or staggered constructions.
The main objective of these barriers was to protect the population and their land from the hostile claims, raids, predations and warlike assaults of other princes. Landwehrs were a clear border marking and, at the same time, when they defined the external border to another territory, also a customs border. Even within a territory, there were sometimes landwehrs which separated the individual districts (Ämter) from one another by the inclusion of streams and other natural obstacles. These 'internal' or 'intermediate' landwehrs (Zwischenlandwehren), were generally not as elaborate as those on the external borders.
Letzi in Näfels, Switzerland
One particular variant was the so-called letzi in Switzerland, where it was often sufficient just to secure the access routes to a valley. Many of the battles of the Old Confederation with the Habsburgs took place at such letzis, such as Battle of Morgarten, Battle of Näfels and Battle of Stoss.
Some landwehrs also functioned as a form of outwork for fortresses. They were built with the character of fieldworks as a first line of defence against enemy attack. Used until the Modern Era, they were designed militarily, in the form of chevaux de frise, to force the attacker of a fortress into having to conduct a siege even before reaching the fortress. Their modern successors include the barbed wire used in both world wars.
The route of many simple landwehrs shows, according to new research, that they were completely unsuitable for defence purposes in many places. From this it can be concluded that some of these installations were mainly used for border marking and collecting customs duties. They nevertheless restricted the free mobility of enemy troops, so that they were certainly of some military utility. For example, the Stadthagen around Warendorf in the Thirty Years' War succeeded in protecting the town. Although the enemy did in fact break into the municipal territory, they did not risk a major attack simply because of the danger, in a counter-attack, of not being able to beat a retreat quickly enough through the narrow breach in the landwehr.
As a border fortification around areas that had been given specific rights, landwehrs had gaps in some places for roads, for counter-attack routes or for trade. These gaps (called Schlags) were guarded by simple tollgates, by side roads (so-called Schlingen),[3] or - by means of towers (watchtowers, Wighäuser or gate towers). At the border crossing points there were usually also customs posts. The lucrative right to charge tolls (Zollrecht), often in connection with the right to sell alcohol (Krugrecht) could be given to local farmers.
Most landwehrs consisted of a simple ditch as an obstacle - on the plains this was also a water channel or moat - behind which was an earthen bank made of the spoil from excavating the ditch. Behind the bank was the main barrier itself, a 20 to 50 metre-wide, dense, impenetrable thicket. In upland areas, the route of the landwehr conformed to natural features such as rocks, steep slopes and watercourses. Often a second ditch was dug at a distance of 10 to 30 metres.
The strips of vegetation and the embankments were covered with a hedge of hornbeam cut back to the height of a man, whose branches were bent, intertwined with the other branches and stuck into the ground as a further obstacle. This resulted in the so-called Gebück, a plaited hedge. Understorey bushes, such as dog rose, whitethorn, blackthorn or brambles, were used to make the hedge impenetrable. Hence the local name, Gedörn ("thorn hedge") used in some places. The site was kept clear of higher vegetation. The ground in front was largely cleared.
The construction of a defensive hedge was described by a priest at Eberbach Abbey in 1790:
The structure was achieved as follows. Trees in the area were cut down to different heights and these were cut back again and their branches bent downwards. These branches continued to grow in their new direction and were closely interwoven, and this subsequently produced such a thick and tangled wilderness that it was impenetrable to men and horses.
—Pater Hermann Bär
With regular maintenance and care (hege), a nigh impenetrable woodland strip was created in the course of a decade. More elaborate landwehrs with a defensive function consisted of several parallel ditches and banks, planted with hedging. In particular, double ditches were designed to prevent them from being jumped by horsemen. Another design was the so-called Wehrhecke (Wallhecke or Knick), a hedge-planted bank, for the maintenance of which a tax called Knickgeld was raised.
In Hesse, at the end of the 17th century, many villages on important roads or by borders, had fortifications, excluding any fortified churches, as a Hessian chronicler described in 1697:
Today is almost the majority of large districts and villages in Hesse are surrounded by a moat and embankment / so that they can defend themselves against minor attacks.
—Johann Just Winkelmann.
The fortification could be made of fences (known as Etter or Dorfetter), hedges, bank and ditch (dry as well as wet) and gates.
Another temporary artificial obstacle which could be built relatively quickly in the event of an attack, or to close gaps in a landwehr, was the abatis. This was also used as the first obstacle on the approach of castles, town and city walls, and schanzen, and was made of felled trees and cut logs, shrubs and thorns. Abatis were also used during the building of a landwehr, if necessary, until it was ready. Since the obstacle was made of dead wood, it was relatively easy to remove by burning once it had dried out.
Important roads passing through the landwehr at entry points were guarded with so-called barriers (Schlägen) and other reinforcements such as watchtowers. Road tolls were collected at the barriers which were paid to the territorial lord. From the beginning there were inns at these points. The innkeepers provided food and drink for the passers-by. They also exercised sovereign functions by observing the ground in front of the town and by closing the barriers at night.
In many cases, the roads were flanked by ditch-bank-ditch systems on both sides, so that no one could enter the villages outside the intended route. Wooden bridges often led across the ditches, so that in the event of a war, the road could be closed by removing the bridge.
News of approaching enemy troops or visitors, was relayed along the landwehrs to the Hinterland, using watchtowers (for example, in Münsterland). In upland regions this was also achieved by observation posts (Warten) at high lookouts from which one could see far into the surrounding countryside. Warning of approaching enemies was given by optical signals in the form of smoke signals, flags, mirrors and torches, or by signal horns and church bells. The entire population of the village and its neighbouring villages were required to "immediately" respond to these emergency signals or the sounding the storm bell, but also in other emergencies, such as fire or flood, no matter what other work or activity was in progress. The striking of the bell was called Gerüfte, for example, in the Münsterland.
Maintenance
Speyer Watchtower, formerly Wormser Warte, northernmost point of the Speyer landwehr, to the west beyond the crossing is the start of the Landwehrstraße, which runs southwestwards.
To construct the landwehr, the local territorial lord would use all his subjects in a service known as socage. Likewise the whole population were required to maintain it. Many landwehrs were built and maintained jointly by neighbouring princes, for example, in Central Hesse, the landheege on the Hörre between the county of Nassau on one side and the Landgraviate of Hesse and county of Solms on the other.
The construction and maintenance of landwehrs had to be carried out with a long-term perspective. Even with constant and time-consuming care (Hegen und Pflegen) it would be ten years before an impenetrable hedge was created. In addition, the ditches and Hählweg, a patrolled road along the landwehr had to be kept free of vegetation and maintained in working order. For this reason, many landwehrs were abandoned or left unfinished for long periods of time for reasons of cost.
Intentional damage of a landwehr was punished with severe penalties. In the case of the over 100-kilometre-long Westphalian Landwehr in the Teutoburg Forest, punishments ranged from cutting off the right hand to the death penalty. Even crossing a landwehr in authorised places was often punished. On the Rhön Landwehr, cutting through the hedging or using the patrol road was punishable by a fine of up to five guilders.
These border installations were constantly renewed and maintained until the 18th century and, in times of extreme danger, even reinforced and turned into fortifications.
In 1813 in Prussia, the obligation to defend the earthworks, which were slighted under Napoleon but nevertheless remained functional, became part of the general service duties of the military formations of the Prussian Landwehr (a territorial force not to be confused with the subject of this article). In many cases the field fortifications of the Landwehr troops were abandoned after the end of an armed conflict or after the abolition of an official district, and the hedges and woods burned to make charcoal.

Approximately 120–150 Neolithic earthworks enclosures are known in Central Europe. They are called Kreisgrabenanlagen in German, or alternatively as roundels. They are mostly confined to the Elbe and Danube basins, in modern-day Germany, Austria, Czech Republic, Slovakia, as well as the adjacent parts of Hungary and Poland, in a stretch of Central European land some 800 km (500 mi) across. They date to the first half of the 5th millennium BC; they are associated with the late Linear Pottery culture and its local successors, the Stroke-ornamented ware and Lengyel cultures. The best known and oldest of these Circular Enclosures is the Goseck circle, constructed c. 4900 BC.
The Province of Westphalia was a province of the Kingdom of Prussia and the Free State of Prussia from 1815 to 1946. In turn, Prussia was the largest component state of the German Empire from 1871 to 1918, of the Weimar Republic and from 1918 to 1933, and of Nazi Germany from 1933 until 1945.

St. Peter is a Romanesque church in Syburg, now a suburb of Dortmund, Germany. It is the active Protestant parish church of Syburg, officially named "Ev. Kirche St. Peter zu Dortmund-Syburg". It serves as a concert venue for the bimonthly Syburger Sonntagsmusiken.
Geographically, the Havelland is the region around which the River Havel flows in a U-shape between Oranienburg to the northeast and Rhinow to the northwest. The northern boundary of the Havelland is formed by the River Rhin and the Rhin Canal. In the history of Brandenburg, the Havelland represents a historic region.
The roundel is an artillery fortification with a rounded or circular plan of a similar height to the adjacent defensive walls. If the fortification is clearly higher than the walls it is called a battery tower.

The Danube–Iller–Rhine Limes or DIRL was a large-scale defensive system of the Roman Empire that was built after the project for the Upper Germanic-Rhaetian Limes in the late 3rd century AD. In a narrower sense the term refers only to the fortifications between Lake Constance and the River Danube (Danubius); in a broader sense it also includes the other Late Roman fortifications along the river Rhine (Rhenus) on the High Rhine and on the Upper Rhine as well as the Upper Danube.
The fortifications of Frankfurt were a system of military defences of the German city of Frankfurt am Main which existed from the Middle Ages into the 19th century. Around 1000 the first city wall was built. It enclosed the area of what is now the Königspfalz in modern Frankfurt. In the twelfth century the settlement expanded into what is now Altstadt. For its protection an additional wall, the Staufenmauer, was erected. Starting in 1333, the Neustadt suburb developed north of the Altstadt and was encompassed by an additional wall with five gates. In the fifteenth century, a "landwehr border" was created around the entire territory of the Free City of Frankfurt. Beginning in 1628, the medieval city wall was developed to form a bastion fortress under the municipal architect Johann Dilich.
The Desenberg near Daseburg in the North Rhine-Westphalian county of Höxter is 343.6 m above sea level (NHN) and the most prominent hill in the Warburg Börde, a relatively level, fertile Börde region. The hill is a basalt knoll crowned by the ruins of Desenberg Castle and a relict of recent geological history and volcanism, as well as medieval feudalism and warfare. The present shape of the Desenberg has arisen through weathering.

Julius Bernhard Stern was a German Jewish banker, art collector and philanthropist.
The Bullengraben is a ditch in Berlin’s glacial valley, which has been in use since the 7th century. It is located in the Berlin district of Spandau and runs from the old village center of Staaken eastwards for about five kilometers to the Havel River, into which it flows north of the Spandau castle rampart. Used for centuries to improve the wetlands, since the 1960s it has been used as a drainage ditch to collect rainwater from the surrounding neighborhoods of Spandau.
The Räuberberg is an archaeological monument, located in Görsdorf within the municipality of Tauche in the Oder-Spree district of Brandenburg, Germany.
Horst Castle, located in the Horst district of Gelsenkirchen, is recognized as one of Westphalia's oldest and most significant Renaissance buildings. During its construction in the 16th century, it ranked among the largest four-winged castle complexes north of the Alps, significantly influencing the architectural style of the Lippe Renaissance. On 15 December 1983 it was declared a listed building.
