Calling all military history buffs! If you think you know your B-17s from your Lancasters, your Mustangs from your Spitfires, London is a city filled with must-see museums.

A visit to the best war museums in London will definitely leave you feeling more informed than ever, and perhaps even have you wishing you could go back to your high school history class. Or, at the very least, you might feel inspired to crack open that history book you picked up in the gift shop.

And if you’re fascinated by the First and Second World Wars in particular, places like the Churchill War Rooms and the Imperial War Museum have enough historic documents, lovingly curated exhibitions, and big guns to keep you entertained for hours.

The Churchill War Rooms: is it worth it?

The bunker from where British government ministers, military strategists and Prime Minister Winston Churchill led the allies to victory in World War II is a London war museum must-see.

The historic rooms, first opened to the public in 1984, are preserved exactly as they once were. Visitors are guided through the winding corridors with a well-crafted audio guide that effectively recreates the tension of the time while recounting the critical decisions made at the height of World War II.

Tickets include access to both the Cabinet War Rooms and the Churchill Museum so that you can better understand the life and work of Britain's best-known Prime Minister. Paid admission.
