Ballyallaban Ring Fort

Ballyallaban Ring Fort is an earth fort, thus the name it is called on maps and by locals: An Rath. Surrounded by a fosse (a generally flooded moat or defensive ditch), the fort was built up and may have had a protective fence of sharp pointed stakes. While earth structures are the most common type of ancient monument in Ireland, they are rare in the rocky Burren area.

An Rath is in good repair and has a very well developed canopy of trees, mainly mature beech, with a deep trench all around which occasionally fills with water.
