Among the most interesting and beautiful places in Ireland special attention, certainly deserve Aran Islands are administratively part of the County Galway), lying off the West coast of the island of Ireland at the entrance to Galway Bay. Given such a location, giving the opportunity to control the coast and the sea for miles around, it is not surprising that the Aran Islands have long been used as an important Outpost. In prehistoric times, the Islands were built FORTS, the ruins of which can still be seen today.

One of these ancient FORTS and is Dun Bhatar ("black stone Fort" or "black round Fort") on the island of Inishmore. The ruins of the Fort of Dun Bhatar lie on a narrow rocky promontory, formed as a result of soil erosion, which, in fact, a huge fortification and disappeared in the coastal waters of Inishmore.

The exact date of construction of the first buildings of Dun Bhatara unknown. Historians believe that the fortress walls, surviving and reaching in some places 6 m high and 5 m wide, were built in the iron age, while the remains of residential structures, hiding behind the walls of the Fort, erected in the early middle ages. Along the exterior walls you can see the remains of the so-called "slingshot" (stone blocks, dug into the ground), established in ancient times as a highly reliable additional protection, able for a while to deter intruders.

Today Dun Bhatar is an important archaeological and architectural monument, and although it is not as popular as the Fort of Dun Angus and is a little bit away from the tourist trail, it is definitely worth a visit.
