One city, fifty-two sanctuaries.
Parks, canals, gardens and rooftops join up into continuous foraging networks. Sites per borough:
Urban sponge roofs absorb stormwater before it overwhelms London.
By planting living soil and hardy wildflowers over bare rooftop asphalt, our 52 sanctuaries act as natural rain sponges and cool the surrounding city air.
