Samlesbury Hall is a historic house in Samlesbury, Lancashire, England, 6 miles (10 km) east of Preston. It was built in 1325 by Gilbert de Southworth (b. 1270) and was the primary home of the Southworth family until the early 1600s.
Samlesbury Hall may have been built to replace an earlier building destroyed during a raid by the Scots in 1322. The hall has been many things in its past including a public house and a girls' boarding school, but since 1925, when it was saved from being demolished for its timber, it has been administered by a registered charitable trust, the Samlesbury Hall Trust. This Grade I listed medieval Manor House attracts more than 50,000 visitors each year. Samlesbury Hall is open to the public daily except on Saturdays.
The house is reputed to be haunted by several ghosts, including that of Lady Dorothy Southworth, who went mad with grief after her lover was killed and secretly buried by her disapproving family. Samlesbury Hall has been investigated twice by Yvette Fielding and her team of investigators on their hit paranormal show, Most Haunted. The first time was during the 5th series in 2005 and the second during a Most Haunted Live event in January 2009. It also appeared in an episode of Ghost Hunters International. Season one episode 10, "Castle of the Damned".
