Reasons for Designation

An enclosure castle is a defended residence or stronghold, built mainly of stone, in which the principal or sole defence comprises the walls and towers bounding the site. Some form of keep may have stood within the enclosure but this was not significant in defensive terms and served mainly to provide accommodation. Larger sites might have more than one line of walling and there are normally mural towers and gatehouses. Outside the walls a ditch, either waterfilled or dry, crossed by bridges may be found. The first enclosure castles were constructed at the time of the Norman Conquest. However, they developed considerably in form during the 12th century when defensive experience gained during the Crusades was applied to their design. The majority of examples were constructed in the 13th century although a few were built as late as the 14th century. Some represent reconstructions of earlier medieval earthwork castles of the motte and bailey type, although others were new creations. They provided strongly defended residences for the king or leading families and occur in both urban and rural situations. Enclosure castles are widely dispersed throughout England, with a slight concentration in Kent and Sussex supporting a vulnerable coast, and a strong concentration along the Welsh border where some of the best examples were built under Edward I. They are rare nationally with only 126 recorded examples. Considerable diversity of form is exhibited with no two examples being exactly alike. With other castle types, they are major medieval monument types which, belonging to the highest levels of society, frequently acted as major administrative centres and formed the foci for developing settlement patterns. Castles generally provide an emotive and evocative link to the past and can provide a valuable educational resource, both with respect to medieval warfare and defence and with respect to wider aspects of medieval society. All examples retaining significant remains of medieval date are considered to be nationally important.

During the 16th century the new use of gunpowder artillery in warfare reduced the effectiveness of traditional fortification. Direct bombardment from cannon meant that even the highest and strongest walls could be demolished. The fortifications of the 16th century accordingly reflect the considerable technical improvements which led to artillery pieces becoming more mobile and accurate combined with specialist roles and greater velocity. Provision was made within existing walls and towers for weapons of heavy calibre to be deployed. In the early forts and towers of Henry VIII firepower was arranged systematically in tiers, in what were elaborate, centrally planned gun towers for all-round defence.

Fortified houses were residences belonging to some of the richest and most powerful members of society. Their design reflects a combination of domestic and military elements. In some instances, the fortifications may be cosmetic additions to an otherwise indefensible high status dwelling, giving a military aspect while remaining practically indefensible. They are associated with individuals or families of high status and their ostentatious architecture often reflects a high level of expenditure. Their buildings normally included a hall used as a communal space for domestic and administrative purposes, kitchens, services and storage areas. In later houses the owners had separate, private living apartments, these often receiving particular architectural emphasis. Fortified houses were constructed in the medieval period, primarily between the 15th and 16th centuries although examples both before and after this period are known.

Despite the fact that parts of the medieval and post-medieval castle at Berwick upon Tweed were levelled in the 19th century significant archaeological deposits survive below ground level as buried deposits and as lengths of upstanding masonry. Due to its strategic importance the castle at Berwick upon Tweed will contribute greatly to our knowledge of the Anglo-Scottish border during the Middle Ages and beyond. Taken with the medieval and post-medieval walls of Berwick upon Tweed it provides one of the most complete overviews available for the understanding of the development of military architecture in Britain.

The monument is situated at the north west corner of the town of Berwick in a commanding position on a steep rise above the estuary of the River Tweed. The main part of the castle which remains standing above ground is in the care of the Secretary of State and includes the west wall of the castle, the south east angle tower known as the Constable Tower and the length of curtain wall adjacent to it, as well as the flanking wall known as the White Wall. All these structures are Listed Grade I. The monument is much more extensive and in addition to the ruins held in Guardianship it includes the remainder of the castle which having been levelled in the 19th century, survives below ground as buried deposits.

The castle is one of the earliest surviving defensive features at Berwick upon Tweed. A castle at Berwick is first mentioned in documents dating to the 12th century, although most of the remains which are visible today date from a re-modelling of the structure in the late 13th and subsequent centuries. When Edward I captured the town of Berwick from the Scots in 1296 the existing castle was strengthened by the replacement of the towers and the addition of others. At this time an additional length of wall known as the White Wall was constructed in order to prevent the castle from being outflanked. This feature abuts the south west angle of the castle and descends the slope to the river side. The castle was further defended on the east side by a deep natural water filled gully. A stone causeway and at various times wooden drawbridges gave access to the castle from a detached tower on the medieval town walls, through the main eastern gateway of the castle which was flanked by two round towers. Berwick and its castle were retaken in 1318 by Robert Bruce who retained it during his lifetime but was lost to England once again in 1333 in the reign of Edward III. The castle which had been damaged was repaired at this time only to suffer further damage when it was occupied on several occasions by the Scots during the 14th century, always to be retaken by the English Crown. The castle and the town were given to Scotland by Queen Margaret in 1461 but was retaken for the last time in 1482 after a long siege and it has remained in English hands ever since.

The castle was garrisoned until the Union of the English and Scottish Crowns in 1603 when the Scottish threat subsided and its military use was largely abandoned. It had been joined to the medieval town of Berwick upon Tweed by a linking wall but had already become separated from the town when the Elizabethan walls were constructed. These defences enclosed a smaller circuit than their predecessors, leaving the castle isolated some distance outside. It is known from documents that new lodgings of a particularly grand design, were constructed in the castle at the beginning of the 17th century. These subsequently become the home of Lord Hume, Lieutenant of the three Scottish Marches, to whom the castle was given in 1604. Documentary evidence shows that the house was tall and square with turrets at each of the four corners or in the centre of each side. It had a very ornate facade and a long west facing upper gallery. Much of the stone and timber from the castle was removed in the mid-17th century when it was used for the building of Holy Trinity, Berwick's new parish church. The ruins of the castle passed from a sequence of private individuals until it became the property of the North British Railway and large areas were levelled in the mid 19th century in order to make way for the railway which linked England and Scotland.

The castle as remodelled after 1296 was formed by an outer enclosing wall strengthened with towers and turrets. Large sections of this wall have been levelled and survive as masonry foundations beneath the current ground level. However, the west wall and parts of the east wall of the castle survive as standing structures. The latter is visible as a length of walling containing four relieving arches surmounted by some modern walling. Attached to the southern end of this wall is the south east angle tower, known as the Constable Tower. The upper courses of this polygonal tower are constructed of weathered ashlar blocks and are equipped with arrow slits suggesting a late 13th century date. A well preserved garderobe chute is visible on its western side. The lower courses of the angle tower are rougher and less regular and are thought to represent the base of an earlier 12th century tower. At the northern end of this length of wall there is a second tower, partly obscured by a deep build up of material. It is visible to a height of six courses above the raised ground level and three visible faces suggest that this is also of polygonal form. The lower part of a narrow arrow slit is visible in one of these faces. The west wall of the castle, some 75m long, is also visible above ground standing to a maximum height of 6m and up to 4m thick. It is faced with roughly coursed ashlar blocks and internally it contains mortices for two levels of timber floor joists. At its northern end are the remains of a semi- circular tower visible as rubble core 12m high with some facing stones in situ. This tower is known as Barmekin Tower. At the southern end of the west wall there is a semi circular mid-16th century gun turret. This turret comprises two floors and the lower level shows the remains of a vaulted ceiling and the upper has the remains of a latrine. The addition of this gun turret to the medieval walls of the castle in the 16th century represents a transition from a medieval form of defensive structure with high walls and flanking towers to one better equipped to deal with the threat posed by the development of artillery warfare. Masonry from the south wall of the castle has been incorporated into the Railway Station retaining wall rebuilt in the 19th century on the line of the castle wall.

Attached to the south west angle of the castle a length of wall, known as the White Wall, descends the steep slopes to the River Tweed where it terminated at a large wooden gate. The wall, 82m long and 6m high, is stepped and contains several narrow arrow slits. A steep flight of steps known as Breakneck Stairs have been constructed against its inner side. During the 16th century the wall was reinforced with additional masonry. A tower constructed at the same time on the site of its medieval predecessor survives well at the present edge of the river. This tower, also of two storeys contains three casements for small cannon. The first floor has three emplacements for guns and the remains of a fireplace. Within the interior of the castle numerous buildings are known to exist from several centuries of use. Domestic ranges, now levelled, survive beneath the ground set against the south and west walls of the castle. Contemporary newspaper reports during the construction of the railway in 1844 describe the uncovering of masonry, some in the form of arches and gateways. When the Royal Border bridge was under construction in 1847 it is reported that a well and the face of a large tower were discovered immediately inside the centre of the south wall of the castle.

A number of features are excluded from the scheduling; these are the station platforms and all structures erected upon them as well as all tracks, sleepers, ballast and gantries for overhead power lines; the surfaces of adjacent railway yards and all other structures contained within or associated with them; also excluded is Station House and its outbuildings and the outbuildings in the grounds of Castle Vale which abut the outer face of the south wall of the monument; the surfaces of all modern roads and carparks, all fence posts, walls and the surfaces of all paths and drive-ways; the ground beneath all of these features is, however, included.
