The sources describe the London Square Open Gardens Weekend as an event designed to grant access to private green spaces across London that are not usually seen by the public. It addresses the fact that a significant portion of London's open areas consists of these private squares and gardens. The event achieves this by making more than a hundred secret green spaces accessible, effectively "prising the keys out of the capital’s secretive gatekeepers". The locations revealed exclusively for the event are diverse, ranging from historical, traditional, contemporary, and experimental spaces. They are situated across all four corners (and the middle bit) of London and include examples such as formal gated garden squares, rooftop terraces with commanding city views, community allotments, and wildlife havens. This event is scheduled for June 7 - 8, 2025.
