Castle Fine Art, Exeter

You'll find Castle Fine Art tucked away in Exeter's city centre, a proper working gallery that takes itself seriously without being pretentious about it. The space itself is well-curated - the kind of place where you can spend twenty minutes or two hours depending on what's on and how deep you want to go into it all. They rotate their exhibitions regularly, so there's a decent chance of finding something fresh if you're a repeat visitor.

The gallery leans toward contemporary work mostly, though you'll see established pieces alongside emerging artists. It's the sort of spot that appeals to serious art types but doesn't alienate people who just fancy a wander round something interesting on a wet afternoon. If you're staying at one of the glamping sites nearby - Devon Heaven Hideaways is only a few miles out - it makes for a solid rainy-day option or a culture break between countryside walks.

Exeter itself has enough going on that you can tie this in with the cathedral, the quay, and decent lunch spots without it feeling forced. Allow forty minutes to an hour here unless there's a particular exhibition that grabs you. It's free to browse, which helps when you're not sure what you're in for. The space has good light and the staff actually seem to know what they're talking about if you have questions. Not essential, but worthwhile if you're already in town.
