The Bishop's Palace, Ely was one of the residences of the Bishop of Ely from the 15th century until 1941. It is a Grade I listed building. The palace was built in the 15th century by Bishop John Alcock however just two towers from the original building remain. He also completed the bishop’s palace (now Wisbech Castle) at Wisbech (where he died in 1500). Bishops over the following centuries expanded and remodelled the palace.
