Ireland

This particular massif has a limestone ground divided up with cracks. Its name comes from the Gaelic word Boireann which means "rocky place".

The dolmen Poulnabrone was a tomb dating back to around -2500 B.C. or -2000 B.C. There are other tombs that can be seen in the surroundings.

We can see Celtic crosses and a round tower, typically Irish, in the churchyard of an ancient monastery. Unfortunately this monastery is now in ruins... This tower is the highest round tower of Ireland still standing, though its a leaning tower. However the visit is quite fast. One can ask the keys to the neighboring houses to visit the inside of the few buildings that can still be closed.
