Run by the charity London Parks and Gardens, the weekend opens the gates on lesser-seen private spaces which enrich London’s landscape. While almost half the capital’s footprint is green, only 18% is designated Public Open Space.
For this one weekend in June, visitors will get to enjoy more than 100 secret gardens across central London which are usually closed to the public. Ticket holders will discover hidden gems, stroll around exquisite roof gardens, uncover gardens belonging to historic institutions, and experience the joy and connections created by community allotments.
This much-loved annual event raises funds to help protect the gorgeous ‘green lungs’ of London; its parks, gardens, squares and hidden green spaces which improve the air we breathe and add value to our lives, our health, culture, and nature.
New gardens for 2025 include:
Battersea Roof Gardens
One of London’s largest residential rooftop gardens, spanning 29,000 sq ft and planted with 23,000 plants and 55 trees, it offers inspiring views of the adjacent Grade II* listed Power Station and London skyline. (Entry by ballot exclusively to London Open Garden ticket holders). Ballot opening dates will be announced to ticket holders in the coming months.
Marlborough House
Formerly a grand town mansion built to a design by Sir Christopher Wren in 1711, it became the headquarters of the Commonwealth Secretariat in 1959. The garden located off The Mall is largely maintained in its 18th century format. Marlborough House returns to London Open Gardens for the first time since 2017.
30 Cannon Street
Short-listed for a RIBA London award, this impressive triangle-shaped roof garden in the City has captivating views of St Paul’s Cathedral, the Square Mile, London and beyond. The garden comprises a mix of shrubs, perennials, grasses and bulbs and houses two beehives. Booking required via timed entry.
Moat Community Garden, Millbank
Part of the Grade 2 listed Millbank Estate near Tate Britain, visitors will discover how local people have used the remains of the former prison moat to create a community garden.
The Sanctuary Garden at Freedom from Torture
A silver medal winner at the Chelsea Flower Show 2024, the garden was relocated to Finsbury Park where it is being used for horticultural and other therapies for survivors of torture.
Returning visitor favourites include:
The Charterhouse Square Garden comprising six courtyard gardens within the Tudor walls of the Charterhouse site, and 25 Cannon Street a mini jewel of a city rooftop space, overlooking the iconic St Paul’s Cathedral; along with a programme of bookable guided walks and cycle tours.
Balloted gardens and high-profile gardens joining the weekend to be announced over the coming weeks.
London Parks and Gardens Interim Director Tim Webb says: “Last year 93% of LOG visitors told us the event reinforced their enjoyment of nature and appreciation of London’s horticultural heritage. We all protect the things we love, so my ambition is to get more Londoners passionate about the spaces around us, the places where nature can and should be. Protecting these green areas from harmful development will protect us from the worst impacts of climate change, adding greater value to our lives.”
