Naval Temple

Tucked into the Forest of Dean near Coleford, the Naval Temple is one of those wonderfully obscure historical oddities that makes you wonder why more people don't know about it. Built in the 18th century, it's a small but striking stone structure that once served as a folly - a monument to naval glory during Britain's maritime heyday. The temple itself is compact, but standing in front of it gives you that genuine sense of stepping back into a very specific moment in English eccentricity.

Historians and heritage enthusiasts will find it genuinely interesting, though families with young children might find a ten-minute visit enough unless they're really into old buildings. The real pull here is the setting - you're deep in proper Forest of Dean woodland, so the journey to reach it becomes part of the experience. Allow an hour if you're combining it with a walk through the surrounding forest.

Bit of a trek getting there, but that's half the charm. The nearest proper base would be one of the campsites - Bracelands, Greenacres, or Doward Park are all within a couple of miles and would give you easy access for exploring both the temple and the forest itself. The monument works best as part of a larger day out rather than a standalone attraction. Bring decent boots and expect muddy paths. If you're staying in the Forest of Dean area, it's well worth hunting down.
