Free things to do in London this weekend

The world’s oldest psychiatric hospital, Bethlem Royal Hospital, often referred to as Bedlam was once a busy public attraction, most famously portrayed in William Hogarth’s ‘A Rake's Progress’. It looked after a number of famous patients including artist Louis Wain and Victorian painter Richard Dadd. Dadd, a former Royal Academy of Schools student and established painter, suffered from delusions whilst on a Middle Eastern tour in 1843, believing the Egyptian god Osiris was influencing him. On his return home, Dadd was taken to Kent to recuperate, but convinced his father was the devil, ended up killing him with a knife before fleeing to France. First detained at Bethlem as a ‘criminal lunatic’ and later moved to Broadmoor Hospital, where he died, Dadd produced some of his most celebrated works, like ‘The Fairy Feller's Master-Stroke' whilst incarcerated. This survey exhibition includes more than 100 works, including rarely seen sketches and paintings and a series of watercolours made on his eastern travels. 

Popping up each summer on the steps where the Regent’s Canal passes Granary Square, Everyman’s Screen on the Canal is one of the city’s best loved outdoor cinemas, thanks to its atmospheric setting, eclectic programming and the fact that it doesn’t cost viewers a penny. Pop down on a sunny afternoon to catch live coverage from Wimbledon every day of the tournament, plus the usual mix of live sports, classic movies, family-friendly flicks and recent hits. So far we know that Devil Wears Prada, Dune: Part One, Some Like It Hot and Paddington in Peru are all on the lineup, and there are plenty more still to be revealed. Best enjoyed with a couple of tinned cocktails and some picky bits from the nearby Waitrose, or classic cinema snacks from Everyman’s on-site bar.  This year, the pop-up has been pimped out by local Kings Cross artist and UAL Central Saint Martin’s graduate Alice Wilson. She’s created a unique folklore-inspired design that will appear across popcorn and the screen itself.   

Battersea Power Station already has an indoor chimney lift experience, a huge food court, a lovely cinema and more high street faves than you can hope to get round in a weekend-long shopping spree. Now it’s adding a free summer funfair to its entertainment offering Electric Summer opens in Power Station Park and along the Coaling Jetty from 29 July, and it’s an entire seaside town’s worth of things crammed onto a Thames-side patch of concrete.  The centrepiece is a full roller rink with sessions ranging from wobbly first-timers to Thursday date nights and Saturday silent discos, plus roller fitness classes if you fancy your cardio with a side of nostalgia. Out on the jetty, pétanque courts turn the riverside into a passable stand-in for the south of France, river views included. There's also a big wheel for skyline views, dodgems, a wave swinger and boardwalk games including Lobster Pot and Blockbuster. We aren’t too sure what either involves, but we’re very intrigued. The Boardwalk Bar’s rooftop terrace is also the obvious spot for an after-work pint with a view. Getting in is free. You only pay if you want to skate or spin around on something.

Once again you can expect to see remarkable feats of astrophotography at the Astronomy Photographer of the Year exhibition. It’s a chance to see magical views of both our own night sky and of galaxies far, far away. The winning spacey visions come from dozens of professional and amateur snappers in various categories including ‘Planets, Comets and Asteroids’, ‘Stars and Nebulae’, ‘Galaxies’ and ‘Young Astronomy Photographer of the Year’ for under-16s. Soar down to Greenwich to see the winners from 2025's competition on display. 

Donald Locke shows don’t come around often. But like proverbial buses, you wait for ages, and then three arrive at once, in the form of this touring exhibition moving from Birmingham to Bristol and now Camden Art Centre in London.  It’s not the first time the late Guyanese-British artist has shown here, though you’d be forgiven for missing it. Back in 1970, Locke exhibited ceramics under the pseudonym Issorosano Ite. He arrived in the UK from Guyana in his mid-twenties to study ceramics in Bath and Edinburgh, even though painting was his initial obsession. ‘With the arrogance of youth, I was going to be the greatest painter in the world,’ he said of his early ambition. Well, he did both, yet what he made doesn’t sit neatly within a single camp. Rather, his practices – spanning painting, drawing, sculpture, and ceramics – would morph into one another. While the forms may appear a little abstract, the thinking behind them is not Take ‘Trophies of Empire’ (1972–74), one of his most iconic works and included in Resistant Forms. An open cabinet of 27 pigeonholes houses dark, cylindrical ceramic forms (bullets, we come to understand) cradled within trophy cups, spurs, and leather cuffs, sourced by Locke from Portobello Market. It’s not the last you’ll see of them. Look at the large, wild, black paintings next door, made a decade or two later while he was living in Phoenix and Atlanta. You’ll spot Queen Victoria, the Warhol-like revolver—now look again: those ‘trophies’ reappear...

The first museum exhibition dedicated to artist Audrey Amiss brings together drawings, paintings and other exhibition materials to explore the life and work of Amiss who died in 2013. Committed to psychiatric hospitals several times throughout her life, Amiss used her art to advocate for people who were mistreated by the mental health system. The Surviving Exhibitions focuses on works that records suggest Amiss exhibited or intended to make public. 

Since its inaugural edition in 1980, this long-standing portaiture competition has attracted more than 40,000 entries from over 100 countries and has been seen by more than six million people. The highly competitive award showcases the best of contemporary portrait painters, whose styles range from the abstract to the classic. Last year the top prize was awarded to British painter Moira Cameron for her non-naturalistic self-portrait, ‘A Life Lived’, which depicts the painter slumped in an armchair in vivid colours.
