Borve Castle, Benbecula

[1] MacGibbon and Ross attributed the building of the tower to Amie mac Ruari, wife of John of Islay, and dated it to between 1344 and 1363.

The walls average 2.75 metres (9 ft) thick, although they narrow internally at the first- and second-storey level.

Its entrance was through a projecting wing in the center of the south wall which opened into the first storey.

The first was a structure with narrow masonry walls in a formal style with regular courses and sandstone quoins.

Next, the eastern side of the castle was reinforced with very wide walls of a moderately formal style with large stones and intermittent coursing, forming an outer skin without windows to the existing structure.
