 Winchester was divided in AD 909, with Wiltshire and Berkshire transferring to the new See of Ramsbury.Nevertheless, the domains of the Bishop of Winchester ran from the south coast to the south bank of the River Thames at Southwark, where the bishop had one of his palaces, making it one of the largest as well as one of the richest sees in the land.In more modern times, the former extent of the Diocese of Winchester was reduced by the formation of a new diocese of Southwark in south London, a new diocese of Guildford in Surrey and a new diocese of Portsmouth in Hampshire.
