Rath na Drinne

This ringfort is just outside Cashel. I include it because it is marked specifically as “Rath Na Drinne” on the OS Map which is unusual and because of its proximity to Carron Henge which is only a few kms away. It is a three bank ring-fort but perhaps it may orginally have been a henge? Its huge in the centre maybe 300-400m diameter.
