St Augustine’s Abbey is the oldest Anglo-Saxon abbey in England. Founded in 597 by St Augustine, it was originally built as a burial site for the Kings of Kent. Largely rebuilt after the Norman Conquest, it began to fall into ruin after the dissolution of the monasteries. Today, it's part of the Canterbury World Heritage Site, which also includes Canterbury Cathedral and St Martin's Church. The site is managed by English Heritage, and they run a museum here.
