All that remains of the Bishops' Palace, which burned down in 1814, is the surrounding wall of the 12C Great Hall, pierced by a graceful 14C rose window and three arcades which opened into the kitchens. The site once included a prison for monks and nuns, under the jurisdiction of the Bishops and located below the high water mark. In the 15C, it was known as the Clink, hence the expression to be in the clink (to be in prison).
