The most visible remains of the ancient monastic settlement of Clondalkin is the round tower. It stands almost 30m tall and it is built from the local calp limestone with door frames being constructed from Leinster granite. Small quantities of sandstone are also included with the tower. A unique buttress of rubble and small stones surrounds the lower portion and the circumference of the tower above this level is 12.7m. The doorway is almost 4m above the road level and has a flat lintel of granite. There are six windows in the tower and the tower’s cap is thought to be mainly original. The tower forms a striking visual feature in the centre of Clondalkin, with the small village roads curving around it carrying modern day traffic and hussle and bustle.
