Abbey Church of St Peter and St Paul
One of the earliest Christian sites in Britain – has been a centre of Christianity since A.D. 634, when St Birinus began a mission to Wessex. The imposing church is all that remains of an Augustinian abbey, founded in 1140. It was enlarged in the 13th and 14th centuries and restored in the I9th. It has good medieval stained glass, a remarkable Jesse window, and a rare lead font.
