Celebrate London's architectural wonders as Open House London throws open the doors of more than 800 buildings and spaces around the capital.
Enjoy free access to public buildings, private houses, churches, museums, schools and offices, and join tours, guided walks and activities throughout the weekend.
You can explore iconic buildings that are not usually open to the public, learn something new about more familiar spaces, and step into the private homes of the rich and famous.
Admission is free to all Open House events, but some venues and tours require advance booking or entry into a public ballot.
