Fort Grey

Fort Grey sits on a rock in Rocquaine Bay, a round white Martello-type tower inside a walled enclosure built in 1804, known locally as the Cup and Saucer for its shape. It now holds a shipwreck museum, which is apt: the Hanois reef offshore has taken a great many ships, and the displays cover the wrecks, the salvage and the lighthouse eventually built to stop them.

What you actually see

• The Cup and Saucer - the round tower inside its circular enclosure.
• The shipwreck museum - displays on the reef's wrecks and salvage.
• The Hanois reef - the rocks offshore the museum is about.
• The tidal setting - a fort on a rock in the bay.

When to go

April to October is when the museum is open; it closes for winter. Tide affects the causeway at the highest waters. Late afternoon light on the white tower is best.

Honest expectations

The museum closes entirely through the winter. It is small and an hour or two covers it. The causeway floods on the biggest tides.
