Malmesbury Abbey in Wiltshire, England was founded as a Benedictine monastery circa 676AD. By the 11th century it contained the second largest library in Europe. It is one of the few English monastic houses with a continual history from the 7th century through to the Dissolution of the Monasteries in the 16th century.
Originally more than three times as large as the building we see today, the monastery boasted a 431 foot spire (taller than Salisbury Cathedral's!). This collapsed in a storm around 1500, demolishing two thirds of the nave and transept and was never repaired. The west tower fell around 1550, destroying the three westernmost bays of the nave, as seen in the picture above.
Today Malmesbury Abbey serves as the parish church.
