Description

Pont Gorswen is a three-span clapper bridge, likely built in the 17th or 18th century. It is constructed from boulders, with natural stone slabs serving as lintels that rest on dry-built piers. There is a parapet on the west side, capped with boulders placed on their ends. The bridge has been widened in recent years.
