Site Overview

History & Significance

Glastonbury Abbey occupies one of the most mythologised sites in British history: a low hill rising from the Somerset Levels, associated since the early medieval period with Joseph of Arimathea, the Holy Grail and King Arthur. Whether or not these legends have any historical substance, the abbey itself was real and immensely powerful. By the Norman Conquest it was the wealthiest monastery in England, its origins stretching back to a possible sixth or seventh-century foundation, and its estates extending across Somerset and beyond.

The great medieval church — one of the largest in England, over 180 metres long — was built after a catastrophic fire in 1184 that destroyed the old Saxon buildings. It was never fully completed before the Dissolution of the Monasteries in 1539, when Henry VIII suppressed Glastonbury and hanged its last abbot, Richard Whiting, on Glastonbury Tor. The ruins that remain today preserve magnificent Romanesque and Early English Gothic stonework. The site gained renewed legendary significance in 1191 when the monks claimed to have discovered the tomb of Arthur and Guinevere — a claim of disputed authenticity but incalculable influence on the Arthurian tradition.

Why it matters

The oldest and wealthiest monastery in medieval England, Glastonbury Abbey was the spiritual and cultural heart of the English church for centuries and the centre of the Arthurian mythological tradition.
