The round tower at Glendalough

The round tower at Glendalough, built sometime in the 11th century, is considered by many to be one of the most finely constructed and beautiful towers in Ireland. Situated in a thickly forested valley, the 30.48 metre tall tower is built of mica schist with a granite doorway. The conical roof was rebuilt in 1876 using the original stones that were found inside the tower. The round tower is divided internally into 6 storeys by timber floors, connected by ladders. The four storeys above entrance level are each lit by a small window; while the top story has four windows facing the cardinal compass points.
