Southwick House (Southwick Park)

  • Earlier Houses: The current house (the third house) replaced an earlier house, the circa 1800 Regency style Southwick Park (the second house; see "Images" section), which was destroyed by fire in 1838. Southwick Park itself replaced a Jacobean house (the first house), built for Colonel Richard Norton and probably demolished in the late 18th or early 19th century. The Jacobean house was built on the remains of a 12th century priory of Augustinian Canons that was sold off as part of the Dissolution of the Monasteries.

    Built / Designed For: Thomas Thistlethwayte, who was described by Viscount Palmerston as "a very stupid but respectable young man possessing considerable property near Portsmouth."

    House & Family History: The current (third) house is a virtual replica of the second house (which burned in 1838), save for the addition of a third floor and different fenestration. In the first years of World War II the Royal Navy used Southwick House to accommodate overnight pupils of the Royal Navy School of Navigation, HMS “Dryad,” which had been based in the nearby Portsmouth Naval Dockyard. In 1943 HMS “Dryad” was moved into the further reaches of the estate and Southwick House became Supreme Headquarters Allied Expeditionary Force. It was here that the primary Allied commanders were based, including General Eisenhower, Field Marshall Montgomery, and Admiral Ramsay, and it was here that Operation Overlord, the Allied invasion of Europe (the largest seaborne invasion in history), was planned. The map room, which contains the top secret maps for the D-Day landings, is today exactly as it was on June 6, 1944. It is because of its extreme historical importance that this room is Grade I-listed.

  • Garden & Outbuildings: The 1707 bird's eye view by Kip (see "Images" section) shows the estate and gardens as laid out in the Dutch style by the actor and theater producer Richard Norton in the late 17th century. This layout, of course, was long ago lost, but it's interesting to see how similar the Southwick orangery appears to the famous Chatsworth orangery. Since 2007 the Royal Military Police Museum has been housed in the stableblock of Southwick House. The museum can be visited by appointment.
