The observatory where the Prime Meridian runs sits on the hill in the park. The ritual is a photo with one foot either side of the metal line in the ground, east and west hemispheres. From the hill in front, the view runs over the Queen's House and the old Royal Naval College to the Canary Wharf towers, one of the best free views in London. Note that the Observatory closes for a long refurbishment from 2 November 2026, so go before then if you want to get inside.
