The Burren Dolmen is situated in north County Cavan, near the border town of Blacklion.
This is on of the best constructed dolmens in Ireland.
Approached from a track running south from Tullygobban Lough into dreary conifer plantation, this tomb is a fine, large and well-preserved example with a gallery over 7 metres long, divided by a high septal slab into a long portico and a large main chamber.
The portal stone is well over 3m tall, so when the capstone was in place this would have been very imposing.
The gallery is covered by 5 roof stones, 3 of which cover the main chamber, and one of which has chock-stones.
The front capstone has a series of depressions which may be artificial cup-marks.
Two of the front orthostats on the faade lean together to form a triangular entrance to the antechamber.
The septal slab has a gap at the bottom of the north end which seems artificial.
The tomb resembles some of the large gallery-tombs (alles-couvertes) of France, and is well worth the trouble of searching for.
It can also be approached from the county Fermanagh side, via a lane leading south west from the Marlbank Scenic Loop to the forest fence.
