Summary

What are probably the remains of a heavily-robbed fort enclose the top of Castlethorn, which forms the local summit of the SW spur of Gormyre Hill. Its rampart has been reduced to little more than a low stony bank, which encloses an oval area measuring about 60m from NNE to SSW by 45m transversely (0.21ha) and includes both the summit of the knoll and a lower terrace on the N. There are also the remains of a bank 2m thick enclosing the summit area, which measures no more than 34m from NE to SW by 26m transversely (0.07ha). The entrance to the fort, which is on the W, is marked by two upright slabs set some 8m apart and measuring 0.6m and 0.5m high respectively.

Investigation History

The two stones flanking the entrance to the inner enclosure were first reported in 1979 by A McLean as standing stones (RCAHMS MS453/55). The enclosure was subsequently photographed from the air by RCAHMS in 1982, 1991 and 2009, and it was also visited in 1985. It was Scheduled in 2005. Kite photography in 2010 and a 3d visualisation in 2014 have been carried out by the West Lothian Archaeological Group (https://www.armadale.org.uk/castlethorn.htm)
