Herlewin’s Tower

You'll find Herlewin's Tower standing alone on the chalk downs just outside Salisbury, a squat Norman fortification that's been here since around the 12th century. It's one of those proper solitary medieval structures that makes you wonder what on earth it was defending out here in the middle of nowhere. The tower itself is small and unassuming - more of a keep than anything grand - but that's precisely why it's worth the trip if you're into genuine Norman architecture rather than the polished castle experience.

The walk to reach it is pleasant enough, across open downland with wide views across Wiltshire. It's not a long haul, but the approach matters more than the destination here. History enthusiasts will get the most from it, particularly those interested in early medieval military engineering. Families with young children might find it a bit sparse - there's no visitor centre, no facilities, and you can see everything in about twenty minutes once you arrive.

There's no charge to visit, and you can access it most of the year without restriction, though the chalk can get boggy after heavy rain so check conditions beforehand. If you're based at one of the nearby sites - Salisbury Camping and Caravanning Club Site is less than half a mile away - it makes for an interesting half-day outing combined with exploring Salisbury's cathedral and medieval streets. Go early morning to avoid fellow walkers and actually feel the isolation the tower was meant to command.
