Looking for more free things to do in London? Here are 102 of em! We've also compiled this epic map of free stuff in London, and have a helpful guide to where to see art in London for free, and where you can catch cheap and free comedy.

Go behind the scenes with two fantastic festivals

Open House London and Heritage Open Days both continue until the end of this week, each offering insights and access to parts of London which are normally off limits.

The Open House programme is vast, but highlights include brewery tours, an open day at Bazalgette's Mausoleum in Wimbledon, guided tours of the Modernist extension to Hackney's German Hospital, a chance to go on the roof at new development Greenford Quay, and a deep-dive into medieval graffiti.

Alternatively, visit the little-known British Vintage Wireless and Television Museum in Dulwich, and be dazzled by its vast collection of radios and goggleboxes.

All events are free, though some do require booking.

Both until 21 September.

Royal Docks Originals

A glowing, life-size tiger, nature-inspired murals, walking tours and trails, a bioluminescent garden and an exhibition about the industrial history of the Royal Docks are among events on the programme at the free Royal Docks Originals festival, which kicks off on Monday showcasing the culture and heritage of the docks area.

It continues next week (and beyond) with a fire garden, hip hop dance performances, a market and more.

15 September-4 October.

Head Beyond Burma... at the National Army Museum

Beyond Burma: Forgotten Armies arrives at Chelsea's National Army Museum, shining a light on the soldiers who fought in Burma (now Myanmar) when it was a vital battleground between British India and Imperial Japan during the Second World War. Personal objects, diaries, artworks, oral histories, weapons, uniforms and photographs explore these lesser-known campaigns which played out during the 1940s.

16 September-13 April 2026.

Experience the riches of the Bank's history

The Bank of England Museum opens its new, free exhibition Building The Bank - 100 Years On from Tuesday. Find out how the Bank's Threadneedle Street home underwent a massive rebuild a century ago, reimagining John Soane's original building when it was no longer fit for purpose.

Once a common foodstuff enjoyed by Londoners from all walks of life, the oyster is inextricably linked to the capital, inspiring everything from Shakespeare's famous epithet ("Why, then the world's mine oyster") to TfL's Oyster cards. A free London Museum Studios session at Smithfield today explores the historical, cultural and environmental significance of the oyster in London's waterways.
