Which garden can you only enter accompanied by children? Where can you find walrus bones, vampire stories and inspiration for red telephone boxes and since when do you see skateboards and mobile phones in roman mosaics? London’s gardens and parks not only form the green lung of the multimillion capital but also its heart and soul. Londoners commemorate their beloved on park benches; they volunteer to keep up community gardens and nature reserves and they get upset when snails attack their favourite plant. The over 400 green spaces in the city are not only testament to the English love of gardening; they are also steeped in history: kings hunted here, airships were built in London parks and many famous Londoners are buried in graveyards turned gardens.
