Selsey Abbey
United Kingdom
Selsey Abbey was founded by St Wilfrid in AD 681 on land donated at Selsey by the local Anglo-Saxon ruler, King Æðelwealh of Sussex. According to the Venerable Bede the Kingdom of Sussex was the last area of mainland England to be evangelised. The abbey became the seat of the Sussex bishopric, until it was moved to Chichester, after 1075 when the Council of London decreed that sees should be centred in cities not in villages. The location of the abbey was probably at the site of, what became, the old parish church at Church Norton just north of modern-day Selsey.
