The Norman Tower (Bury St Edmunds)

The Norman Tower, also known as St James' Gate, is the detached bell tower of St Edmundsbury Cathedral, Bury St Edmunds, Suffolk. Originally constructed in the early 12th century, as the gatehouse of the vast Abbey of Bury St Edmunds, it is one of only two surviving structures of the Abbey, the other being Abbey Gate, located 150 metres to the north. The Abbey itself lies in ruins, approximately 200 metres to the east. As a virtually unaltered structure of the Romanesque age, the tower is both a Grade I listed building and a Scheduled Ancient Monument. The tower is considered amongst the finest Norman structures in East Anglia.
