The Luitpold Tower (German : Luitpoldturm or Luitpoldsturm) was erected in 1909 on the summit of one of the highest hills in the Palatine Forest, the 610-metre-high Weißenberg [1] as an observation tower. It is made of bunter sandstone.

German language West Germanic language

German is a West Germanic language that is mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, South Tyrol (Italy), the German-speaking Community of Belgium, and Liechtenstein. It is also one of the three official languages of Luxembourg and a co-official language in the Opole Voivodeship in Poland. The languages which are most similar to German are the other members of the West Germanic language branch: Afrikaans, Dutch, English, the Frisian languages, Low German/Low Saxon, Luxembourgish, and Yiddish. There are also strong similarities in vocabulary with Danish, Norwegian and Swedish, although those belong to the North Germanic group. German is the second most widely spoken Germanic language, after English.

Observation tower structure used to view events from a long distance

An observation tower is a structure used to view events from a long distance and to create a full 360 degree range of vision to conduct the long distance observations. They are usually at least 20 metres (66 ft) tall and made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in Germany at the end of the 18th century, and their numbers steadily increased, especially after the invention of the lift.

History and construction

Tablet with dates and construction history of the Luitpold Tower

The idea of building a tower was conceived on 29 May 1895 at the general assembly of the Gräfenstein Conservation Society (Gräfensteiner Verschönerungsverein), a group that forestry assessor August Zwissler from Leimen had founded in 1893. It was decided to build a viewing tower on the Weißenberg costing an estimated 8,000 to 10,000 gold marks. The necessary funding would be raised by society member Martin Jäger, a well known local poet who went under the pseudonym, Fritz Claus. Thanks to his support for the tower he was able to win the Palatine Forest Club, founded in 1902 in Ludwigshafen, to his cause. The leadership of the PWV took over the coordination of the project, had the plans produced by architect Ludwig Ullmann and gathered the necessary funding, predominantly from membership subscriptions. Its name was proposed by Karl Albrecht von Ritter, the chairman of the PWV at the time; it was named after Prince Luitpold of Bavaria. [2] In 1908 construction on the tower began and it was inaugurated on 26 September 1909. [3] The costs came to around 23,000 gold marks, which corresponds to a sum of about €250,000 in 2000. [4] The payment of this amount was concluded in 1911 by the Palatine Forest Club. [5]

German gold mark german currency from 1871-1914

The Goldmark was the currency used in the German Empire from 1873 to 1914. The Papiermark refers to the German currency from 4 August 1914 when the link between the Mark and gold was abandoned.

Palatine Forest Club organization

The Palatine Forest Club is a hiking club in the former Bavarian Palatinate, i.e. the southern part of the German state of Rhineland-Palatinate and the Saarland county of Saarpfalz-Kreis. In 2011 it had 221 local branches with around 27,000 members.

Luitpold, Prince Regent of Bavaria Ruler of Bavaria

Luitpold, Prince Regent of Bavaria, was the de facto ruler of Bavaria from 1886 to 1912, due to the incapacity of his nephews, King Ludwig II for three days and King Otto for 26 years.

The Luitpold Tower is a rectangular structure built of hewn sandstone blocks and comprises a perron, the actual observation tower itself and an attached building annexe The tower is 34.6 metres high, and the viewing platform is 28.5 metres above ground level. From platform level there is a further, small staircase tower with a door and slate roof.

Sandstone A clastic sedimentary rock composed mostly of sand-sized particles

Sandstone is a clastic sedimentary rock composed mainly of sand-sized mineral particles or rock fragments.

Perron (staircase) outdoor stairway

A perron in architecture generally refers to an external stairway to a building. Curl notes three more-specific usages: the platform-landing reached by symmetrical flights of steps leading to the piano nobile of a building; the steps themselves; or the platform base of edifices like a market cross.

The annexe

After climbing the perron, the visitor enters a staircase tower, well-lit by multiple window openings. There are 164 steps to the observation deck. Halfway up, there is a small oriel window with a bench that can be used to rest. The upper portion of the tower is occupied by a spacious room with a relatively narrow, metallic spiral staircase in the centre, leading to the top. The visitor leaves the staircase turret through a metal door and finally enters the viewing platform, which is surrounded by a sandstone balustrade, approximately waist high, with four observation niches. In 2002, 12 tablets were mounted on this parapet at regular intervals, which point out places of interest that may be seen from the tower, both close to and in the far distance, together with distance information.

Staircase tower

A staircase tower or stair tower is a tower-like wing of a building with a circular or polygonal plan that contains a stairwell, usually a helical staircase.

Observation deck

An observation deck, observation platform or viewing platform is an elevated sightseeing platform usually situated upon a tall architectural structure such as a skyscraper or observation tower. Observation decks are sometimes enclosed from weather, and a few may include coin-operated telescopes for viewing distant features.

Oriel window type of bay window

An oriel window is a form of bay window which protrudes from the main wall of a building but does not reach to the ground. Supported by corbels, brackets, or similar, an oriel window is most commonly found projecting from an upper floor but is also sometimes used on the ground floor.

At the foot of the tower is an annexe, intended as a resting place and also as a refuge in case of inclement weather. It contains a stone table and benches, a fireplace and a plaque on which essential data about the tower and its architectural history are documented.

Renovation and conservation

The building has been protected since 1993 and was thoroughly renovated in 2000 and 2001. This entailed improving the structural geometry of the tower and adding a concrete ceiling to the viewing platform. There was also no way round a modification to the iron spiral staircase and a renewal of the roof. The overall cost came to €230,000, almost the same amount originally needed for the construction of the tower. Upon completion of these renovations, the tower was opened to the public again in a ceremony on 28 August 2001. [6]

Structural analysis is the determination of the effects of loads on physical structures and their components. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, vehicles, furniture, attire, soil strata, prostheses and biological tissue. Structural analysis employs the fields of applied mechanics, materials science and applied mathematics to compute a structure's deformations, internal forces, stresses, support reactions, accelerations, and stability. The results of the analysis are used to verify a structure's fitness for use, often precluding physical tests. Structural analysis is thus a key part of the engineering design of structures.

Reinforced concrete composite building material

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed, so as to improve the behaviour of the final structure under working loads. In the United States, the most common methods of doing this are known as pre-tensioning and post-tensioning.

To support the longer term maintenance of the tower, the Luitpold Tower Club (Luitpoldturmverein) was set up in 2007. Its aim is to "conserve, and where possible improve, the structural state of the tower ... to ensure free access to the tower at any time as well an unobstructed panoramic view for all ... and to keep the public aware of the tower and the extensive views that can be experienced." [7]

Location and views

The tower stands on the territory of the municipality of Merzalben in the middle of the Palatine Forest at the highest point of the Weißenberg (610 m above sea level (NN)). The tower is 1.4 kilometres from Hermersbergerhof and may be reached on foot in 10 to 20 minutes. In good weather 457 named places can be identified: in the Palatinate, in the state of Baden-Württemberg, in French Alsace and the Saarland, [8] and the viewing platform has 12 direction tables that enable easy orientation. In good conditions, for example, the following may be seen: the Donnersberg (highest peak in the Palatinate region, 42 km distant, visibility ca. 42%), the Kalmit (highest mountain in the Palatine Forest, 20 km, visibility ca. 82%,), the Donon (highest mountain of the northern Vosges, 96 km, visibility ca. 8%) and the Hornisgrinde (highest mountain in the northern Black Forest, 77 km, visibility ca. 14%).

Walking routes in the Palatine Forest

Walking routes in the Palatine Forest fall into two categories. The first are longer walking routes, most of which are maintained by the Palatine Forest Club, or PWV, and which are linked to the national and international network of long distance paths. The second category are those local circular walks and themed walking routes, some of which are of wider regional importance, and which are maintained by municipal authorities. The Palatine Forest, as part of the Palatine Forest-North Vosges Biosphere Reserve, is an important conservation area. As a result, the Palatine Forest, the bunter sandstone landscape of the Palatine Forest Nature Park, the castles in the Dahner Felsenland and the cross-border paths into Alsace and the Vosges make the region particularly popular with ramblers and walkers.
