Castor isn’t new, it’s been plugging away down in Deptford for ages, but it is newly central, having upped sticks from south-east London and moved into the heart of Fitzrovia in autumn 2022. Deptford’s loss is everyone else’s gain, though, because Castor’s new location makes its programme of exhibitions – filled with awesome younger artists like Tom Worsfold, Jane Hayes Greenwood and Rafal Zajko – infinitely more accessible.
