London, England: Whitehall Street and Churchill War Rooms

Whitehall, Britain's most important street connects Parliament with Trafalgar Square. A walk here is chock-full of reminders of a proud and hard-fought history as you pass monuments, Royal Horseguards and the nearby Churchill War Rooms. Shut down after WWII, it's open today as a fascinating time warp for visitors to explore.
