The last remaining part of the building after which Newcastle was named, 12th-century Castle Keep has superb views across the city center and bridges over the Tyne. Much of the older castle was pillaged for building materials by enterprising locals building nearby shops and houses (subsequently demolished) in the 17th and 18th-centuries but the 13th-century Black Gate remains largely untouched. Visitors explore the Great Hall, with its 19th-century vaulted ceiling, and the museum.
