Oxford Castle is a large, partly ruined Norman castle in Oxfordshire, England. Most of the castle was destroyed in the English Civil War, and by the 18th century, the remaining buildings had become Oxford's local prison.
The prison closed in 1996 and was redeveloped as a hotel and visitor attraction. The medieval remains of the castle, including St. George's Tower and crypt, as well as the motte, are Grade I listed buildings and a Scheduled Monument.
Blenheim Palace is a British national treasure located in Oxfordshire, England, UK. It was the birthplace of the first Duke's famous descendant, Winston Churchill. Visitors today can explore the State Rooms, art galleries and 2,000 acres of gardens.
