London Open Gardens is an annual event held in June, giving us a rare chance to step through private gates and discover beautiful, little-known places, the ‘secrets’ of the city that become temporarily public during the event.
Today, DOYOUSPEAKLONDON brings you the top highlights from the unforgettable 2025 edition!
London Open Gardens
London Open Gardens is an annual June event organised by the charity London Parks and Gardens. It offers a rare access to over 100 private and tucked-away green spaces across the city.
From elegant garden squares to secluded courtyards and leafy rooftops, it’s a unique chance to explore London’s hidden natural gems that are usually closed to the public.
This was my first time taking part in the event, and I felt incredibly lucky to explore some amazing hidden spots, which I’m excited to share with you now!
It’s good to know that all the money raised goes directly towards supporting the charity’s mission to protect and promote London’s historic green spaces. They want to make sure they continue to thrive and stay accessible for everyone, both now and for generations to come.
25 Cannon Street Rooftop
This was one of those unexpected “wow” moments. Hidden high above the city buzz, the 25 Cannon Street rooftop revealed itself as a peaceful green haven.
Normally reserved for office occupants, this beautifully designed space was opened to the public for just one day during London Open Gardens. Such a rare treat!
I couldn’t get over the panoramic views of St Paul’s Cathedral and the surrounding skyline, including The Shard and the City. It felt like a secret garden floating above London. Definitely one of my favourite surprises of the weekend!
To complement the rooftop terrace, open to the public just once a year via London Open Gardens, don’t miss the Reflection Garden (see above, by day and by night) at ground level.
Designed in 2022 by renowned landscape architect Tom Stuart‑Smith, it features a tranquil reflecting pool perfectly framing St Paul’s Cathedral. This is one of my favourite London spots for photography!
Bunhill Fields Historic & Wildlife Garden
I was genuinely surprised by this spot. Once a burial ground, it is now a peaceful haven for wildlife.
Birds hop through the trees, bees buzz around the flowers, and you can really feel the history all around you!
It’s the final resting place of literary greats like William Blake and Daniel Defoe, making it feel both deeply historic and quietly alive.
A must-see for book lovers, history buffs, and anyone who enjoys wandering through places with real soul!
The Aga Khan Centre
The Aga Khan Centre really blew me away! It’s such an amazing piece of architecture and feels like a calm little oasis right in the middle of bustling King’s Cross!
Designed by renowned architect Fumihiko Maki and opened in 2018, it beautifully bridges cultures, with Prince Charles and the Aga Khan IV there to mark the occasion.
The building hides six stunning Islamic-inspired gardens, across rooftops, terraces, and courtyards, each echoing the traditions of Morocco, Persia, Spain, and India. A peaceful thread of green woven into the city. I found this place absolutely stunning!
The best part? You can visit this place year-round on guided tours! A rare chance to experience Islamic-inspired design in a stunning modern setting!
Ham Yard Hotel rooftop terrace
The Ham Yard Hotel Terrace is seriously something special.
Imagine a hidden rooftop garden that feels like a little slice of Provence, with olive trees, colourful flowers, fresh herbs, and yep, they even have a beehive buzzing away up there!
It’s the perfect spot to relax, soak in the sun, and enjoy a drink while surrounded by greenery, all above the bustling streets of London.
Visiting these rooftops and hidden gardens really gives you a whole new perspective on the city. It’s like discovering secret pockets of nature and calm tucked away above or behind the usual urban chaos.
Battersea Power Station Rooftop
One of the standout experiences was the Battersea Power Station rooftop!
This iconic industrial landmark has been transformed into a vibrant new hub, and the rooftop garden gives you a spectacular, elevated view of the Thames and the London skyline.
It’s a mix of modern landscaping and industrial charm, with plenty of seating areas and greenery that make it feel both contemporary and peaceful.
Walking around, you can appreciate the scale of the restoration work and the creativity involved in turning a historic power station into a space that’s open, green, and welcoming.
Visiting during London Open Gardens felt extra special because these kinds of rooftops aren’t usually open to the public, giving a rare glimpse into how London blends heritage and modern urban design.
Chelsea Markham Square Private Garden
Chelsea Markham Square offers a truly hidden oasis in the heart of one of London’s most famous neighbourhoods.
Stepping through the private gates, you are immediately immersed in an elegant garden with mature trees, colorful flower beds, and perfectly manicured lawns.
It’s a peaceful escape from the bustle of Chelsea, and walking through the garden, you can really appreciate the careful design and personal touches that make this space unique.
Visiting during London Open Gardens is a rare privilege, as private gardens like this are usually off-limits to the public.
It’s a must-see for garden enthusiasts and anyone who loves discovering the secret corners of London.
London Open Gardens is more than just a tour of beautiful spaces, it’s an opportunity to connect with the city in a way that’s usually impossible, to see its hidden beauty, and to appreciate the care and creativity that goes into maintaining these serene spots.
