Passacaglia

You won't find Passacaglia listed in most guidebooks, which is rather the point. This Sussex gallery sits just outside Brighton and trades in contemporary art that actually makes you think instead of just photograph well for Instagram. The space itself is intimate - more living room than sterile white cube - which means you're forced into genuine engagement with whatever's on the walls.

The gallery rotates exhibitions regularly, so what you see depends entirely on when you visit. That's either brilliant or frustrating depending on your mood. I'd ring ahead before making the trip, especially if you're camping nearby at Pegs and Pitches or Brighton Caravan and Motorhome Club Campsite - both are less than two miles away.

Who should bother? Art-minded types will absolutely get it. Families with teenagers interested in contemporary work, yes. If you're after something to fill an hour between lunch and the beach, it might feel a bit too contemplative. There's no gift shop, no café, no pressure to consume anything except the art itself.

It works brilliantly as part of a Brighton cultural day - combine it with the seafront galleries and you've got a proper afternoon sorted. Chalky Downs Campsite three miles out gives you that breathing room if you're doing the tourist circuit but want somewhere quieter to sleep. Check opening hours are sensible before you drive over - this is the sort of place that occasionally closes for artist residencies or private viewings.
