Open House London is opening the doors of some of the capital’s most famous and exciting architecture. For one weekend only, over 800 buildings, neighbourhood walks and architects talks will be taking place across the capital’s landscape. What’s more, the tours are completely free, so why not view London from within the famous landmarks themselves. This tour offers a mooch around some of London's best Roman remains which were first discovered in 1848. It's true a good bath never gets old. This event is free and entry is on a first come first served basis, so it can't be guaranteed. We need your card details to store the event information in your profile, but rest assured, we won't charge you a penny.
