Fort Southwick, D-Day Bunker, Portsmouth - Underground Guided Tour, 10am

Built in 1942 as a Combined Operations Headquarters, this huge underground bunker, hidden deep beneath Portsdown Hill and Victorian Fort Southwick, was the operations centre that coordinated the D-Day Landings. This labyrinth of tunnels was home to 700 men and women of the Royal Navy, Army, RAF and Allied nations that directed Operation Neptune - the naval phase of D-Day. The Fort Southwick UGHQ had a direct link to nearby Southwick Park where Supreme Commander General Eisenhower was based in the weeks leading up to D-Day. Information from the UGHQ Operations Room was relayed and duplicated in the Southwick Park Operations Room, giving Eisenhower the latest situational information on the Normandy Beaches and English Channel.
