Summary of site:
This natural bridge over the County River is formed in the Knockmore Limestone Member of the Dartry Limestone and may be the remains of the roof of an earlier cave. There are small caves in both banks of the river and there is also a rift aligned with a major joint at right angles to the river. The bridge is about 8m long and 4m wide and appears to be associated with an archaeological site and monastic remains in the immediate area. The bridge spans the border between Co. Fermanagh and Co. Leitrim.
