Glastonbury Tor is a hill in Glastonbury, Somerset, England, which features the roofless St Michael's Tower and forms an iconic part of the local landscape. The spot seems to have been called "Ynys yr Afalon" (meaning "The Isle of Avalon") by the Britons and is believed by some to be the Avalon of Arthurian legend. Remains of a 5th-century fort have been found on the Tor. This was replaced by the medieval St. Michael's church that remained until 1275. An earthquake was recorded on 11 September 1275, which destroyed the church. A second church, built in the 1360s, survived until the Dissolution of the Monasteries in 1539 when the Tor was the place of the execution of Richard Whiting, the last Abbot of Glastonbury Abbey. He was hanged, drawn and quartered along with two of his monks, John Thorne and Roger James. The remains of St. Michael's Tower were restored in modern times.
