Glastonbury Tor rises to 525 feet and the tower at its summit is all that remains of the 14th century
church dedicated to St Michael. After the Dissolution of the Monasteries in 1539 the church became a
ruin, but the tower was restored in the 18th century. Glastonbury is located in the Somerset levels and in
the Dark Ages it would have been surrounded by marshland. This is one reason why the Tor is associated
with the Isle of Avalon, where the mythical King Arthur came to be healed of his wounds after defeating
his nephew Mordred at the Battle of Camlan. The Tor is also said to be the home of Gwyn ap Nudd,
the Lord of the Underworld. It is maintained by the National Trust.
