Bastioned fort in Jamestown

Located on top of a drumlin overlooking Jamestown, which is c. 170m to the E at the nearest point. A fort with a wide view over the countryside and the town would be an essential part of the defences of Jamestown and might have been constructed at the outset in 1620, but the earliest secure reference to a garrison at Jamestown is in 1646 when it had a complement of a hundred men and their officers (Mahaffey 1901, 654). In September 1689 Col. Thomas Lloyd, on a raid from Sligo town, took Jamestown without a fight for King William as defending Jacobite troops had fled overnight. He left a colonel Russell in charge of a token force, which abandoned the town at Sarsfield’s approach the next month, but there was no fighting at Jamestown (Wauchope 1992, 76-81). The fort is a rectangular earthen platform (dims 20m E-W; 17.5m N-S; H 0.6-1m) with slight banks at N (Wth 2.5m; int. H 0.3m; ext. H 0.7m) and S (Wth 4.3m; int. H 0.5m; ext. H 1.2m). There are rectangular bastions (dims of top 9.5-10.5m N-S; 5-7m E-W) offset in two directions at each angle. The bastions are defined by scarps (H 0.6-1.2m), and the fort is surrounded by a slight fosse indicated by lush vegetation forming a rectangular area (max. ext. dims 40m E-W; 36m N-S). The fort is cut by a N-S field bank towards the W edge, and it is grass-covered W of this feature but is generally overgrown to the E.
