Kilclooney Dolmen is a Portal Tomb built more than 4000 years ago. It is a fine example of the oldest kind of monument found in Northwest Europe, so it is much older than Stonehenge. Other impressive examples of Portal Tombs are found in this vicinity.
Doon Fort is an impressive 4.8m high walled enclosure, forming a rough oval on a small island in Doon Lough. The tradition to which this fort belongs is now reckoned to date from 1000BC.
