Sophia Spring’s photographs celebrate how London’s many parks became a lifeline for locals during the pandemic, writes novelist David Nicholls

We didn’t call it the park; it was the “rec”, as in “recreation ground”. A flat, featureless oblong of patchy grass, sodden in winter, parched in summer, scattered with ring-pulls and dog mess – this was the late 70s – its great featureless expanse broken only by buckled goalposts and a few skinny, unclimbable trees. I hated the rec, partly because of the threat of team sports, partly because of the possibility of violence – the two seemed to go together – but during those long, endless days of summer, when the glare of sunlight on the TV screen became too much, we were harried out of the house to “get some fresh air”. And so we loitered on that great barren prairie, an immense waiting room, wondering why anyone would go to the park out of choice.

Last summer, there were queues at the gates of Clissold Park and anyone wanting to exercise in Highbury Fields was advised to go early to avoid the rush hour. All over the city, the parks began to resemble the sites of the festivals that had all been cancelled and if Londoners had ever taken their green spaces for granted, there was no danger of that now. In the space of six months, they’d been repurposed as meeting rooms, nightclubs, concert halls, theatres and cinemas, cafes and restaurants, impromptu markets, family living rooms, gyms. London is supposedly a city of 3,000 parks and while I’m a little sceptical of that number, it’s true that the city had never seemed greener than that summer. On early morning bike rides I discovered Bushy and Ruskin and Trent, Peckham Rye and Beckenham Place and Ladywell Fields. I discovered the canals and waterways that link them too, the bloodstream of London, captured so brilliantly by Sophia in these photographs. Walk north on the Lea, west or east on the Grand Union, south on the Wandle or the Waterlink Way and you can see the ghosts of London’s old industries, cranes and disused warehouses and old pumping stations. Keep walking for the rest of the day, under the pylons and past the depots, and you can feel the city fading behind you, the skies opening up.
