Architecture and continuing use
The rectangular tower is about forty feet high and rises to an embattled parapet carried on a corbelled wall head. Its compact masonry mass and elevated setting preserve the defensive character of a late-medieval lordly residence.
Its story
Lord Maxwell built the tower in the mid-fifteenth century. It was converted for church use in the late 1960s, followed by construction of a new church beside it in the early 1970s. The national reassessment in 2013 recorded the tower as unused.
Why it is included
Category A listing recognises a nationally important medieval tower house whose later ecclesiastical setting adds an unusual chapter to its history.
What to notice
- The corbelled wall head supporting the parapet.
- Embattlements giving the roof line a defensive outline.
- The close contrast between medieval tower and twentieth-century church.
Reading the surroundings
Do not assume the castle interior is open. Use only access advertised by the congregation, keep clear of worship and private functions, and avoid steep or restricted ground.
