In 1940, Winston Churchill declared the Cabinet War Room “the room from which I will direct the war,” and he wasn’t wrong—this underground hideaway was a crucial command center from which the British government orchestrated the country’s war efforts. Today, the Churchill War Museums are among the most acclaimed WWII museums in London. Peek inside the secret network of war bunkers: visit the Map Room, Transatlantic Telephone Room, and Cabinet Rooms.

Step aboard the HMS Belfast and take a deep-dive into Britain’s seafaring history as you explore the huge WWII warship. This Royal Navy warship was not only used during D-Day, but it later served during the Korean War and carried out humanitarian assignments before becoming a floating museum in 1971. Once on board, you can visit all nine decks, climb the ladders into the crew’s quarters, and admire views across the Thames.

Hampton Court Palace is best known as the grand Tudor residence of one of Britain’s most notorious kings, the five-times-married King Henry VIII. If you’re visiting WWII memorials in London, you’ll want to also include a walking or bike tour around Hampton Court Palace Gardens and Bushy Park. During WWII, the royal parklands were home to Camp Griffiss, a US Air Force and Army base from where General Eisenhower planned the D-Day Landings.

Some of the city’s most important war memorials are dotted along Whitehall, and visiting with a London WWII history sites guide provides insight into the parliamentary district.

Hop on the tube and head up to the north London neighborhood of Barnet, where the Royal Air Force (RAF) Museum has plenty to excite aviation enthusiasts. More than 100 aircraft are on display at the Hendon Aerodrome, including a Supermarine Spitfire Mk 1A and a Hawker Hurricane Mk 1 that took part in the Battle of Britain. Learn about the role of fighter pilots, bombers, seaplanes, and helicopters during WWII and beyond, or take a seat in the cockpit of a Spitfire.

Christopher Wren’s architectural masterpiece is not only one of London’s most famous landmarks, but it also served as an important symbol of hope and resilience for Londoners during WWII. The magnificent St. Paul's Cathedral was repeatedly under attack during The Blitz, when daily German bombing raids left much of the city in ruins. However, despite a Nazi bomb piercing the cathedral’s dome and damaging the high altar, the sacred monument stood strong.

Another one of the United Kingdom’s most important military museums is found in the affluent West London borough of Chelsea. Tucked away between Chelsea’s historic streets and foodie spots, the National Army Museum chronicles the history of the British Army, following them through colonial wars, civil wars, and both world wars. In addition to learning about the role of British battalions during WWII, there’s a fascinating exhibition devoted to the work of British soldiers in post-WWII Germany.
