About The Round Tower
Clondalkin Round Tower is about 1000 years old. It was built in the centre of an early medieval monastery, which was originally founded by St Crónán Mo-Chua in the late 600s or early 700s.
No one knows for certain why round towers were built or what they were used for. But most likely, they were mainly used as bell towers.
The tower is 27.5 meters high and just four meters wide at the bottom. Like others around the country, Clondalkin Round Tower has a raised doorway and four windows at the top, which face towards the four compass points: north, south, east and west.
Inside there were once six floors, which were all connected with ladders. There are now five floors, and the original openings for the door and windows all survive.
