 A 14-bedroom house (Bishop's House) on Eastgate was the official residence in use from 1948 until 2011, when the bishop's office staff and home were separated, allowing the incoming bishop, Christopher Lowson, to live in a modern five-bedroom house.A further residence of the mediaeval Bishops of Lincoln was Banbury Castle, built in 1135 by Alexander of Lincoln, Bishop of Lincoln and retained by the see until 1547.The Anglo-Saxon dioceses of Lindsey and Leicester were established when the large Diocese of Mercia was divided in the late 7th century into the bishoprics of Lichfield and Leicester (for Mercia itself), Worcester (for the Hwicce), Hereford (for the Magonsæte) and Lindsey (for the Lindisfaras).
