A Roman siege tower or breaching tower (or in the Middle Ages, a belfry[1]) is a specialized siege engine, constructed to protect assailants and ladders while approaching the defensive walls of a fortification. The tower was often rectangular with four wheels with its height roughly equal to that of the wall or sometimes higher to allow archers or crossbowmen to stand on top of the tower and shoot arrows or quarrels into the fortification. Because the towers were wooden and thus flammable, they had to have some non-flammable covering of iron or fresh animal skins.[1]
The siege tower sometimes housed spearmen, pikemen, and swordsmen or archers and crossbowmen, who shot arrows and quarrels at the defenders. Because of the size of the tower it would often be the first target of large stone catapults, but it had its own projectiles with which to retaliate.[1]
Siege towers were used to get troops over an enemy curtain wall. When a siege tower was near a wall, it would drop a gangplank between it and the wall. Troops could then rush onto the walls and into the castle or city. Some siege towers also had battering rams which they used to bash down the defensive walls around a city or a castle gate.
Ancient use
In the First Intermediate Period tomb of General Intef at Thebes (modern Luxor, Egypt), a mobile siege tower is shown in the battle scenes.[2] In modern Harpoot, Turkey, an artistically Akkadian style stone carved relief dated circa 2000 BC was found depicting a siege tower, the earliest known visual depiction from Anatolia (although siege towers were later described in Hittite cuneiform writing).[3]

Siege towers were used by the armies of the Neo-Assyrian Empire in the 9th century BC, under Ashurnasirpal II (r. 884 BC – 859 BC). Reliefs from his reign, and subsequent reigns, depict siege towers in use with a number of other siege works, including ramps and battering rams.
Roman siege tower
Centuries after they were employed in Assyria, the use of the siege tower spread throughout the Mediterranean. During the siege of Memphis in the 8th century BC, siege towers were built by Kush for the army led by Piye (founder of the Nubian25th dynasty), in order to enhance the efficiency of Kushite archers and slingers.[4] After leaving Thebes, Piye's first objective was besieging Ashmunein. Having assembled his army for their lack of success so far, the King then undertook the personal supervision of operations including the erection of a siege tower from which Kushite archers could fire down into the city.[5]
During the siege of Syracuse in 413 BC, Athenians erected a siege tower on ship hull. Alexander did the same at Tyre (322 BC) as did Marcellus in Syracuse (214 BC).[6] Towers were used against both land and naval targets. At the time of Emperor Aggripa, ship towers were built with a lighter, collapsible design that could be stowed flat on the deck when not in use, lowering the center of gravity.[6][7]
The biggest siege towers of antiquity, such as the Hellenistic GreekHelepolis (meaning "The Taker of Cities" in Greek) of the siege of Rhodes in 305 BC by Demetrius I of Macedon, could be as high as 40m (130ft) and as wide as 20m (66ft). Such large engines would require a rack and pinion to be moved effectively. It was manned by 200 soldiers and was divided into nine stories; the different levels housed various types of catapults and ballistae. Subsequent siege towers down through the centuries often had similar engines.
However, large siege towers could be defeated by the defenders by flooding the ground in front of the wall, creating a moat that caused the tower to get bogged in the mud. The siege of Rhodes illustrates the important point that the larger siege towers needed level ground. Many castles and hill-top towns and forts were virtually invulnerable to siege tower attack simply due to topography. Smaller siege towers might be used on top of siege-mounds, made of earth, rubble and timber mounds in order to overtop a defensive wall. For example, the remains of such a siege-ramp at Masada, Israel built by the Romans during the siege of Masada (72–73 AD) have survived and can still be seen today.
On the other hand, almost all the largest cities were on large rivers, or the coast, and so did have part of their circuit wall vulnerable to these towers. Furthermore, the tower for such a target might be prefabricated elsewhere and brought dismantled to the target city by water. In some rare circumstances, such towers were mounted on ships to assault the coastal wall of a city: at the Roman siege of Cyzicus during the Third Mithridatic War, for example, towers were used in conjunction with more conventional siege weapons.[8]
One of the oldest references to the mobile siege tower in Ancient China was a written dialogue primarily discussing naval warfare. In the Chinese Yuejueshu (Lost Records of the State of Yue) written by the later Han dynasty author Yuan Kang in the year 52 AD, Wu Zixu (526 BC – 484 BC) purportedly discussed different ship types with King Helü of Wu (r. 514 BC – 496 BC) while explaining military preparedness. Before labeling the types of warships used, Wu said:
Nowadays in training naval forces we use the tactics of land forces for the best effect. Thus great wing ships correspond to the army's heavy chariots, little wing ships to light chariots, stomach strikers to battering rams, castle ships to mobile assault towers, and bridge ships to light cavalry.
And in the section from the Polyandrion Gate as far as the Gate of St Romanus he prepared to station twelve lofty siege towers, which were advanced almost as far as the outworks, and he covered them with hides.
At this siege, the attackers also made use mobile armoured shelters known as sows or cats, which were used throughout the medieval period and allowed workers to fill in moats with protection from the defenders (thus levelling the ground for the siege towers to be moved to the walls). However, the construction of a sloping talus at the base of a castle wall (as was common in crusader fortification[11]) could have reduced the effectiveness of this tactic to an extent.
Siege towers also became more elaborate during the medieval period; at the siege of Kenilworth in 1266, for example, 200 archers and 11 catapults operated from a single tower.[1] Even then, the siege lasted almost a year, making it the longest siege in all of English history. They were not invulnerable either, as during the Fall of Constantinople in 1453, Ottoman siege towers were sprayed by the defenders with Greek fire.[10]
Siege towers became vulnerable and obsolete with the development of large cannon. They had only ever existed to get assaulting troops over high walls and towers and large cannons also made high walls obsolete as fortification took a new direction. However, later constructions known as battery towers took on a similar role in the gunpowder age; like siege-towers, these were built out of wood on-site for mounting siege artillery. One of these was built by the Russianmilitary engineerIvan Vyrodkov during the siege of Kazan in 1552 (as part of the Russo-Kazan Wars), and could hold ten large-calibre cannon and fifty lighter cannons.[12] Likely, it was a development of the gulyay-gorod (that is a mobile fortification assembled on wagons or sleds from prefabricated wall-sized shields with holes for cannons). Later battery towers were often used by the UkrainianCossacks.
During the Imjin War, the Japanese utilized siege towers to scale the walls of Jinju but were beaten back several times by Korean cannons.[13][14] In the early 19th century, the Joseon Army utilized siege towers to lay siege to Jeonju where the last of Hong Gyeong-Rae’s Rebellion made their stand but were beaten back several times by the rebels.[15]
Modern parallels

In modern warfare, some vehicles used by police tactical units, counterterrorists, and special forces can be fitted with mechanical assault ladders with ramps. These are essentially modernized siege towers with elements of escalade ladders, and are used to raid a structure through its upper levels. These assault ladders are not as large or as tall as their predecessors, and are typically only capable of reaching roughly the third or fourth floor of a structure.
On 1 March 2007, police officers entered Ungdomshuset in Copenhagen, Denmark using boom cranes in a manner similar to siege towers. The officers were placed in containers that the crane operators raised and placed against the structure's windows, from which the officers then entered.[16]

Medieval warfare is the warfare of the Middle Ages. Technological, cultural, and social advancements had forced a severe transformation in the character of warfare from antiquity, changing military tactics and the role of cavalry and artillery. In terms of fortification, the Middle Ages saw the emergence of the castle in Europe, which then spread to the Holy Land.
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or by well-prepared assault. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy.
A battering ram is a siege engine that originated in ancient times and was designed to break open the masonry walls of fortifications or splinter their wooden gates. In its simplest form, a battering ram is just a large, heavy log carried by several people and propelled with force against an obstacle; the ram would be sufficient to damage the target if the log were massive enough and/or it were moved quickly enough. Later rams encased the log in an arrow-proof, fire-resistant canopy mounted on wheels. Inside the canopy, the log was swung from suspensory chains or ropes.
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars usually consider a castle to be the private fortified residence of a lord or noble. This is distinct from a mansion, palace and villa, whose main purpose was exclusively for pleasance and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were commonplace.
A defensive wall is a fortification usually used to protect a city, town or other settlement from potential aggressors. The walls can range from simple palisades or earthworks to extensive military fortifications such as curtain walls with towers, bastions and gates for access to the city. From ancient to modern times, they were used to enclose settlements. Generally, these are referred to as city walls or town walls, although there were also walls, such as the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasian Wall, and the Atlantic Wall, which extended far beyond the borders of a city and were used to enclose regions or mark territorial boundaries. In mountainous terrain, defensive walls such as letzis were used in combination with castles to seal valleys from potential attack. Beyond their defensive utility, many walls also had important symbolic functions – representing the status and independence of the communities they embraced.
A fortification is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin fortis ("strong") and facere.
A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls and other fortifications in siege warfare. Some are immobile, constructed in place to attack enemy fortifications from a distance, while others have wheels to enable advancing up to the enemy fortification. There are many distinct types, such as siege towers that allow foot soldiers to scale walls and attack the defenders, battering rams that damage walls or gates, and large ranged weapons that attack from a distance by launching projectiles. Some complex siege engines were combinations of these types.
Ancient warfare is war that was conducted from the beginning of recorded history to the end of the ancient period. The difference between prehistoric and ancient warfare is more organization oriented than technology oriented. The development of first city-states, and then empires, allowed warfare to change dramatically. Beginning in Mesopotamia, states produced sufficient agricultural surplus. This allowed full-time ruling elites and military commanders to emerge. While the bulk of military forces were still farmers, the society could portion off each year. Thus, organized armies developed for the first time. These new armies were able to help states grow in size and become increasingly centralized.
Roman siege engines were, for the most part, adapted from Hellenistic siege technology. Relatively small efforts were made to develop the technology; however, the Romans brought an unrelentingly aggressive style to siege warfare that brought them repeated success. Up to the first century BC, the Romans utilized siege weapons only as required and relied for the most part on ladders, towers and rams to assault a fortified town. Ballistae were also employed, but held no permanent place within a legion's roster, until later in the republic, and were used sparingly. Julius Caesar took great interest in the integration of advanced siege engines, organizing their use for optimal battlefield efficiency.
The Mesopotamian Civilization had an adept grasp of tactics. In fact, they are the first confirmed users of the shield wall tactic later made famous as the classical Greek phalanx and the Roman "testudo formation". It is unknown who first developed this tactic, but it is thought to have been developed somewhere between 2500 B.C.E and 2000 B.C.E
A bastion fort or trace italienne is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield. It was first seen in the mid-fifteenth century in Italy. Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era.
Gunpowder artillery in the Middle Ages primarily consisted of the introduction of the cannon, large tubular firearms designed to fire a heavy projectile over a long distance. Guns, bombs, rockets and cannons were first invented in China during the Han and Song dynasties and then later spread to Europe and the Middle East during the period.
The Neo-Assyrian Empire arose in the 10th century BC. Ashurnasirpal II is credited for utilizing sound strategy in his wars of conquest. While aiming to secure defensible frontiers, he would launch raids further inland against his opponents as a means of securing economic benefit, as he did when campaigning in the Levant. The result meant that the economic prosperity of the region would fuel the Assyrian war machine.
The siege of Motya took place in summer 398 BC in western Sicily. Dionysius, after securing peace with Carthage in 405 BC, had steadily increased his military power and had tightened his grip on Syracuse. He had fortified Syracuse against sieges and had created a large army of mercenaries and a large fleet, in addition to employing the catapult and quinqueremes for the first time in history. In 398 BC, he attacked and sacked the Phoenician city of Motya despite the Carthaginian relief effort led by Himilco. Carthage also lost most of her territorial gains secured in 405 BC after Dionysius declared war on Carthage in 398 BC.
African military systems before 1800 refers to the evolution of military systems on the African continent prior to 1800, with emphasis on the role of indigenous states and peoples, whose leaders and fighting forces were born on the continent, with their main military bases, fortifications, and supply sources based on or deriving from the continent, and whose operations were conducted within the continental mass or close to its borders or coasts. Development of the military arts in this framework generally moved from the simple to the more sophisticated as economies and cultures became more elaborate. Areas such as Carthage, Egypt and Nubia are reflected in the antiquarian period. The pre-colonial period also saw a number of military systems- from cavalry empires on the grasslands, to kingdoms in more tropical and forested areas. The emergence of the gunpowder era, alongside developments in indigenous organization and culture, was to spark far-reaching consequences cutting across all regions, with ripple effects in culture, politics and economies.
The sambuca was a ship-borne siege engine which was invented by Heracleides of Tarentum and was first used unsuccessfully by Marcus Claudius Marcellus during the Roman siege of Syracuse in 213 BC.
Warfare in Medieval Scotland includes all military activity in the modern borders of Scotland, or by forces originating in the region, between the departure of the Romans in the fifth century and the adoption of the innovations of the Renaissance in the early sixteenth century. In this period conflict developed from minor raids to major conflicts, incorporating many of the innovations of continental warfare.
This is an overview of Chinese siege weapons.
Nubia is a region along the Nile river encompassing the area between the first cataract of the Nile as well as the confluence of the blue and white Niles or, more strictly, Al Dabbah. Nubia was the seat of several civilizations of ancient Africa, including the Kerma culture, the kingdom of Kush, Nobatia, Makuria and Alodia.
Siegecraft originated in Ancient Greece. This type of siege originated from the moment in which the stage of the mere siege was surpassed by an exceptional development of military techniques, which were hardly taken any further during the Middle Ages, until the invention of firearms. The importance of siege techniques was due to the increase in the strategic role of the city to the detriment of the territory in the overall defense of the polis.
