Admiral's Walk is a mock-Tudor country house in Pirbright, in the county of Surrey, England. It was built in the early 1900s, in the style of an Elizabethan manor house, and named after an avenue of Scots pines planted by the explorer Vice-Admiral John Byron. It stands on high ground within an estate of 33 acres, which in 1966 included 10 acres of formal and terraced gardens. Former residents have included the private solicitor to George V, Sir Bernard Halsey-Bircham, and the businessman Sir Adrian Jarvis, 2nd Baronet. In the 1970s, it was the principal filming location for three British horror sexploitation films, Virgin Witch, Satan's Slave and Terror.
