With more than 800 buildings usually closed to the public opened up for public viewing, Open House London is one of the biggest architectural festivals in the world. It celebrates our curiosity for what happens inside the buildings that we walk past every day and their architectural history.
Each year, over a quarter of a million people take advantage of this festival to glimpse London’s hidden treasures, take tours, and listen to talks throughout the city. Lots of spaces require pre-booking, so get on it if there are particular buildings you’re keen to visit.

Don’t worry if you don’t manage to bag a ticket though, there are plenty of drop-in venues, walks and cycling tours you can just turn up to.

Check out the full listings on their website for more details.
