Overview
Nestled just 100 yards from the Lough Foyle ferry landing at Greencastle Harbour, County Donegal, the Inishowen Maritime Museum & Planetarium occupies the former Coast Guard Station that once watched over the busy Greencastle‑Magilligan route. The compact cultural hub offers dramatic harbour views, a climate‑controlled museum chronicling the peninsula’s maritime legacy, and a state‑of‑the‑art full‑dome planetarium that projects everything from accurate night‑sky simulations to prehistoric sea‑monster spectacles. It makes an ideal stop on the Wild Atlantic Way or any Donegal itinerary.
History & Background
The early‑20th‑century Coast Guard building was originally erected to monitor shipping lanes in Lough Foyle and to assist vessels in distress. After falling out of use, local volunteers recognised its potential as a heritage centre. In 2013 the structure reopened as the Inishowen Maritime Museum, its collection growing from donations by former coast‑guard families, fishermen and maritime historians. A decade later, a modern planetarium dome was added, funded in part by a €232,000 grant from the Shared Island Coast‑to‑Coast Capital Investment Scheme. The museum now tells the story of the region’s boat‑building, wartime convoys, emigration, and the famous 1588 Spanish Armada wrecks, while the planetarium brings the heavens and ancient oceans to life.
