The incident occurred at Grianan Fort, a stone ring fort dating to 1700 B.C.
Only two men from the group were arrested. They were found guilty and sentenced to a month in jail, suspended for one year. They also had to pay damages. The two were caught because they lingered at the fort after the rest of the drunks had left. A police officer arrived to find them pulling stones from the prehistoric walls and lobbing them into the parking lot.Grianan Fort is set atop a high hill. It is the best-preserved fort of its kind and is widely believed to have been the seat of the ancient Kingdom of Aileach. The walls are 15 feet thick and 16 feet high, so while the drunks were able to cause cosmetic damage, they didn’t destabilize the ancient structure.
The holy well at the fort is dedicated to Saint Patrick and is one of many throughout Europe that are receiving renewed attention. The holy well at Binsey, Oxfordshire, for example, was all but abandoned a decade ago but is now attracting pilgrims who pray to the local Saint Frideswide for cures to their illnesses.
