Step inside a 14th-century Anglo-Norman fortress overlooking Lough Foyle, then explore Ireland's maritime heritage in the neighbouring museum — all with a private local historian as your guide.
What to expect
Your private guide meets you steps from the pier at the 14th-century Greencastle Fort, one of the best-preserved Anglo-Norman castles in Ireland. You walk the curtain walls above Lough Foyle with commentary on Viking raids, the Gaelic chieftains and the Plantation era. The adjacent Inishowen Maritime Museum houses rare navigation instruments, a Breeches Buoy rescue display and a remarkable collection of Armada artefacts recovered from the Donegal coast. The combination of castle ruin and maritime story, guided one-to-one, is deeply immersive.
Good to know
The museum and fort are literally at the harbour — ideal if you want a rich half-day that leaves the afternoon free. Contact the museum directly to arrange private guided access. Check seasonal opening hours before sailing.
