Counter-castles were built in theMiddle Ages to counter the power of a hostile neighbour or as asiege castle, that is, a fortified base from which attacks could be launched on a nearby enemy castle.
In castle science, and according to mediaeval usage, a counter-castle was a type of castle that was built to secure a territorial lord's claims to power or tobesiege and conquer the estates of rival rulers. In such cases, it may also be referred to as a siege castle. These terms are not used uniformly by specialist authors. Usually a distinction is made between counter-castles and siege castles. Where this is the case, a siege castle refers to one built near the enemy castle within the range oftrebuchets andcatapults that could act as a strongpoint, a route barrier, a refuge in the event of counter-attacks, abarracks and a battery position for ballistic weapons.
A counter-castle is often used to describe a castle that was built at a greater distance from enemy fortifications and castles. It did not support the immediate siege of a castle, but was constructed as a base in an area of rival power in order to prevent enemy attempts to expand their influence and control.
Siege castles are only evident from the period of theLate Middle Ages onwards. They were usually built as a temporary fortifications using wood and earth above the castle to be captured and within sight and the range of their guns. From this location the target would be bombarded.
Sometimes only a trebuchet position was established instead of a masonry or wooden siege castle. A favourable point in the terrain, within range of the besieged castle, was levelled and lightly fortified. From this position, the enemy castle could be engaged relatively safely with a trebuchet or catapult and its occupants psychologically ground down. Such a position may be seen today about 430 metres northeast and aboveThurant Castle on theMoselle.
Trebuchets were used in sieges from the early 13th century. Large catapults had a range of about 400 to 500 metres. However, only wealthyfeudal lords could finance the use of such a large, costly siege engine or even the construction of a counter-castle.
Only occasionally did the attackers have the time and financial resources to build their fortress of stone. Rare examples areRamstein Castle, theRauschenburg atMermuth in theHunsrück andTrutzeltz Castle. The last-named was built during theEltz Feud as a counter-castle toEltz. The Rauschenburg was also built in connection with the Eltz Feud as counter castle to the castles ofEhrenburg,Waldeck andSchöneck.
In the majority of known cases, siege castles were abandoned after the fighting and fell into disrepair. Sometimes the lord of the formerly besieged castle was given the counter-castle in a peace agreement or even took it over as afief, as in the case of Trutzeltz Castle. In exceptional cases, such structures were - when the conquest was successful - expanded into independent castles. Examples include theHohenfels andSchadeck Castle atRunkel on theLahn.
The few surviving stone counter or siege castles generally show evidence of less careful construction. In order to build the fortification quickly, clay was mixed with the lime mortar. These defences are therefore dangerous today in view of their condition and can be made safe through painstaking renovation.
Academic research has only investigated counter and siege castles to any great extent since the end of the 20th century. After scholars like Joachim Zeune had concerned themselves in the 1980s and 1990s more with the symbolism of medieval fortifications, subsequent research began to be more critical of the then established theses. As part of the new focus on the functional and military aspects of military architecture, the counter castle became more of a focus of military historical interest.
TheNorman Conquest of England had undergone long preparation and is generally reckoned as one of the most notable military-strategic campaigns of the earlyHigh Middle Ages. TheNormans attacked the island just at the time when the English were busy defending a Norwegian attack in the north. The English Army under KingHarold succeeded in repelling theVikings but now exhausted, had to fight roughly 7,000 well-equipped Norman warriors.
During the invasion numerous simple 'occupation castles' were built, the first, at Pevensey, being at the landing-place of William's army. In addition tomottes,circular ramparts withpalisades were built and olderCeltic orSaxon fortifications were reactivated. The wooden components of these wood and earth castles had in some cases been prepared on the continent and were later assembled on the spot. This enabled the rapid establishment of a dense network of military strongpoints, some of which were later turned into stone castles.
These castles can be made out on the famousBayeux Tapestry. Occasionally even the barrels are depicted in which the invaders transported nails for the construction of forts on the other side ofthe Channel.
Right at the start ofhis conquest of Celtic Wales, the English king, Edward I, ordered in 1277 the construction of several castles at strategically important places. Among these early English castles of occupation were those inAberystwyth,Builth,Flint andRhuddlan.
The outbreak of new unrest in 1282 caused the king to initiate a huge construction programme. The English Army was accompanied by 355 carpenters, 70 stonemasons, and 1,000 stone breakers and earthworks builders. In addition, 1,700 lumberjacks were gathered from the whole of England. After a year this force was increased by 25 carpenters and 100 stonemasons.
Within a short period of time a complete network of the most modern fortifications sprang up, which are today seen as the epitome of mediaevalprofane architecture. With supplies coming in from the sea, these strongpoints enabled the land to be secured militarily. The Welsh castle-building programme cost huge sums of money that had to be raised byparliament and even the church. A subsequent plan to defeat Scotland in the same way foundered due to the cost of such a building campaign.
Among the most important English occupation castles were those of built byJames of St. George includingCaernarfon,Conway andHarlech.
During the siege of larger, fortified cities and towns castles were sometimes built as protection againstsallies andrelief troops.
During theFirst Crusade the Crusaders built the first siege castles before the gates of Islamic towns and cities in theHoly Land. In 1097 Malregard Castle was built in front of the St. Paul's Gate atAntioch.[1] A little later the castles ofla Mahomerie andTancred's Castle were built in front of other gateways.
In 1103Raymond IV of Toulouse ordered the construction of the siege castle,Mons Pelegrinus, atTripoli. Raymond was the Count of St. Gilles, which is why the castle in the centre of the town is known locally asQualat Sandjill.
As well as siege castles, counter-castles were also built at greater distance from the besieged towns. For example, in 1117, KingBaldwin I built a counter-castle"ad coercendum praedictam urbem" (to conquer the aforementioned town) ofTyre nearİskenderun. Despite this siege Tyre did not fall until 1124.
The king also attempted to monitor the importantcaravan route of Derb el-Hadj from several new castles. Here the Pilgrim's Way ran toMecca andMedina. AroundPetra the castles ofMontreal/Shobaq (1115) andLi Vaux Moisee were built and, in 1116, fortified strongpoints were added atAqaba and on theIsle de Graye/Jazirat Fara’un.
In 1142, construction started on the mighty fortress ofKerak (Krak de Moab) in northern Transjordan, to which a harbour on theDead Sea belonged. From hereRaynald of Châtillon undertook numerous raids in the surrounding area. In retaliation, SultanSaladin attacked the Frankish crusader states.
Between 1136 and 1142 four strong castles (atCastrum Arnaldi,Beth Gibelin,Ibelin andBlanchegarde) were built around the Egyptian-held city ofAshkelon.
In theHoly Roman Empire, the termTrutzburg was commonly used to describe the defensive character of a castle that defied all attacks. The word is also used in German as a metaphor for things that are especially durable and resistant.
Where theTrutzburg was built specifically with the object of besieging enemy fortifications it was also known as aGegenburg ("counter castle"),Okkupationsburg ("occupation castle") orBelagerungsburg ("siege castle"). These terms are used today by modern castle scientists and researchers in preference to the more genericTrutzburg.
