A 17th-century gun tower on Tresco, built low and round to withstand cannon fire rather than to look impressive - though reviewers say it does that too, perched over Caribbean-blue water on the island's west coast. There's no entry fee and no staff; you reach it via a coastal path from the harbour.
Climbing the tight spiral stair to the gun platform on the roof - reviewers say it's the closest you'll get to knowing what it felt like to be stationed there.
It's a 30-minute walk along a narrow coastal path from the harbour, with no facilities at the site - worth pairing with the walk up to King Charles's Castle further along the hill.
Reviewers consistently describe Cromwell's Castle as a picturesque, well-preserved ruin worth the coastal walk from the harbour, with several highlighting the chance to climb to the gun platform on the roof for excellent island views. No caveats or complaints appear in the available reviews, visitors seem uniformly charmed by its dramatic setting and free entry.
