This is what remains of the largest Roman residence yet discovered in Britain. Built around A.D. 75 in villa style, it has many mosaic-floored rooms and even an under-floor heating system. The gardens have been restored to their original 1st-century plan. The story of the site is told both by an audiovisual program and by text in the museum. Guided tours are offered twice a day. (See what an archaeological dig in July 1996 unearthed.) In 2006, the attraction underwent a multimillion-dollar redevelopment; it now offers a state-of-the-art computer graphic reconstruction of the palace. Roman artifacts are on display in the Discovery Centre.
