Southwick House, a new manor house was completed in 1813. This house was gutted by fire in 1838, and was renovated and rebuilt by 1841. The house and part of the estate was requisitioned by the government during World War II, when the house was Eisenhower's SHAEF headquarters for Overlord, the cross-channel invasion of Normandy. The house has been used by various branches of the armed forces, including as HMS Dryad, ever since.
