This fort is also located on the edge of a high cliff, it’s situated at the southern side of Inis Mór. The construcion consists of a extended part which was defended by a bended wall and a “chevaux de fries”. (These are razor sharp stones and they are standing upright. It’s almost impossible to penetrate between these stones) There are still remains of stone houses visible at the interior.
There are also a series of long rectangular buildings next to the extended part of the fort, these are probably used as cattle yards in a later period. This type of fort dates back to the Iron Age and the construction can be situated between 200 BC and 500 AD.
Because archaeologists found here some pottery, they believe that it’s possible that there was already a small settlement there before the fort. The integration of the houses on the inner face of the enclose suggests that the fort was occupied in the early Medieval period (9th - 10th century).
This was the first fort we visited. It's the nicest one I think because - unlike Dun Aengus - its not full of tourists. When we were there on a nice sunny morning we were almost on our own :-)
