Tutanota 22

A contemporary art gallery tucked into the Monmouthshire countryside near Chepstow, Tutanota 22 showcases rotating exhibitions of work by emerging and established artists. The space itself is modest - not a cathedral of modern art, but genuinely intimate. You'll find everything from painting and sculpture to installation pieces, depending on what's on when you visit.

It's the sort of place that rewards a slow wander rather than a quick tick-off. Expect to spend forty minutes to an hour properly looking around, longer if there's a piece that really grabs you. The gallery attracts serious art types and curious locals in equal measure, so it never feels overstuffed with people.

Admission details aren't widely published online, which is either refreshingly low-key or slightly frustrating depending on your view. Worth ringing ahead before making the trip. If you're based at Penhein Glamping down the road, it's an easy drive over and makes a pleasant break from the usual holiday park routine - lets you feel a bit cultured without having to trek into Cardiff.

Chepstow itself is close by, so you could couple this with the castle or a riverside walk. Monmouthshire has proper depth if you're staying a few days. The gallery works best if you're already interested in contemporary art rather than as a rainy-day backup plan.
