Broch of Borwick

The broch has an external diameter of 17 metres and an internal diameter of 8 metres. The walls which are 3.5 to 5 metres thick currently stand to a maximum height of 2.6 metres. The eastern half of the broch and the entrance passage are well preserved, but the western half has been destroyed by erosion. The entrance passage, which is still lintelled over, is 5.6 metres long with door-checks each formed of a slab set on edge 3 metres from the outside. A guard cell opened off the right of the passage. The broch was once cut off from the flat land beyond by an outer wall, and there were outbuildings between the wall and the broch.
