Bothal Castle Remains of Curtain Wall to South of Residential Block

Bothal Castle features the remains of a curtain wall located to the south of the residential block. This wall includes sections that likely date back to the Bertram 'mansum', which predates the 1343 license to crenellate, as well as parts from the later medieval period. There has been 19th-century patching and repair work. The wall is constructed from squared stone of varying quality and forms a long, irregular enclosure at the top of a natural hill.

The east curtain, which is adjacent to the south-east angle of the gatehouse, has two external buttresses. Beyond this, there is a rounded projection that leads to a 19th-century retaining wall, which incorporates older masonry towards the south-east corner. The south wall displays a chamfered plinth, likely from the south-east tower, and features higher walling with angle buttresses and blocked chamfered windows at the south-east corner of the bailey.

At the center of the west side, a 19th-century garden wall connects to the west curtain, which is 1.6 meters thick and rises up to 7.5 meters high. This section contains remnants of two fireplaces and a set of moulded corbels on its internal face. The north end of the west curtain connects to the 19th-century wing that is attached to the gatehouse.
