I love this tree.
Round Towers are unique Christian architectural features in Ireland, probably derived from visits to Europe and seeing the great bell towers. At Glendelough in County Wicklow near St. Kevin's Church is the Round Tower. At over 110 feet, it is one of the largest in the country. They were built between the 10th - 12th centuries and are believed to have been used as places of refuge and storage for valuables. The doorway was usually 12 feet above ground and reached by a removable ladder, as were each of the floors inside. Although legend has it that their principle function was to keep out marauding Vikings from attacking, it was probably more likely that it was a status symbol of the importance of the church or monastery associated with the tower.
Going up to this tower was very tiring and the stairs were very narrow. But in the end it was all worth it, once I was up there it was such in incredible view. I loved visiting this site and I wish I could go back and redo it again.
