Lost Oasis

This Summer 2026, get ready for Lost Oasis: an immersive urban sanctuary within the grounds of St Martin-in-the-Fields overlooking Trafalgar Square which will turn the concrete heart of Central London into a lush, sprawling haven of greenery and high-end food, sport and entertainment.

In collaboration with Cornwall’s iconic The Lost Gardens of Heligan, one of Britain’s best-loved and romantic gardens, and in partnership with Blue Forest, Lost Oasis is an immersive experience designed by some of the world’s leading landscape designers that goes beyond the traditional pop-up.

Inside a series of beautifully crafted timber structures woven with vibrant planting, Lost Oasis will host an impressive programme including a rotating line-up of top chefs including Nathan Outlaw, Simon Stallard, Jordan Bailey, Emily Scott, Adam Handling MBE and Sally Abé, alongside a schedule of major sports screenings including the FIFA World Cup, Wimbledon screenings and a special event for the Formula 1 British Grand Prix, plus live music provided by Sofar Sounds, live comedy and more.

At the heart of the experience sits The Mud Maid Bar, the showpiece and striking focal point of Lost Oasis, inspired by the signature artwork of The Lost Gardens of Heligan by sculptors Sue and Pete Hill. Nearby, the Cornish Orchard Cider Tree offers a playful and immersive twist, inviting guests to pour their own pint directly from a sculptural cider tree. Tucked beneath the Treehouse, The Whispering Bar provides a more intimate escape, dedicated to rosé, wine and strawberry-led serves.

At its centre, a planted garden space with climbing greenery and pollinator-friendly installations will provide a more informal setting for day-to-evening use, from after-work drinks to ticketed events. The site is a living garden of climbing vines and flowers between Heligan installations featuring planters of mixed materials, living walls with green spaces and homes for pollinators throughout. Lost Oasis will be a casual retreat for after work wind downs with friends and a host for exclusive events.

The Lost Oasis Food & Drink line-up is as follows:
