The post of Archdeacon of Chichester was created in the 12th century, although the Diocese of Sussex was founded by St Wilfrid, the exiled Bishop of York, in AD 681. The original location of the see was in Selsey. The see was moved to Chichester, in about 1075, by decree of the Synod of London. Currently, Luke Irvine-Capel is the Archdeacon.
