One of the most unique museum experiences in London, the former Cabinet War Rooms are now known as the Churchill War Rooms. An education for all ages allows you to walk through the subterranean, former British war offices (right under the City of London!) used by the dedicated men and women who served under Winston Churchill’s brave leadership during the Second World War. Don’t miss the additional, modern and mesmerizing exhibits in all their ‘super-tech’ glory. It is one of my favorite museums in London.
