Remains of Fallowlees Bastle, Hollinghill. Photo by Peter Ryder.

The remains of a post-medieval bastle stand in an isolated position at the head of the River Font. Only the north-west and south-west walls still stand, with the remaining walls only visible as foundations. The standing walls contain some original features, such as narrow, slit windows. Remains of a probable enclosure wall lie to the north. This is a Scheduled Monument protected by law.
