"This early christian settlement was founded by St. Declan in the 5th Century, and may have been prior to the arrival of St. Patrick in Ireland. The 'Archaelogical Inventory of Co. Waterford' P.164 notes the following :

The round tower which was built in the 12th Century stands at 29 metres high and is comprised of four floors. There are four windows on the top floor of the tower, each being equi-distant from each other. There are a number of simpler openings on the other floors, which also provide light. The entrance doorway is roughly four metres from the ground. The round tower was to serve as a refuge for inhabitants of the settlement and was also used a safe storage location for their various possessions, which would have included books, chalices etc" Source - Waterford County Museum
