Bishop's Palace
The Bishop's Eye gate leading from Market Place takes you to the magnificent, moat-ringed Bishop's Palace, which retains parts of the original 13th-century residence. The peaceful grounds command the most attention, including the gatehouse, the ramparts, and the impressive remains of a late-13th-century great hall that fell into ruin after the lead in its roof was sold in the 16th century. On the right of the gatehouse, note the bell hanging over the moat: swans have learned to ring it at feeding time (usually around 1 pm).
Most palace rooms are closed to the public, but you can see the impressively vaulted undercroft, the private chapel, and, atop the Jacobean staircase, the Long Gallery, hung with portraits of bishops past and present. Check the website (or call) for details on free tours of the palace and gardens (up to four daily, at 11 am, noon, 2 pm, and 3 pm) and the program of events and outdoor productions held throughout the year.
