About North Down Museum
The museum occupies the old laundry and stables at the rear of Bangor Castle, built for the Hon. Robert Edward Ward in 1852. The castle itself now serves as the town hall, and the museum sits within the surrounding Castle Park grounds.
Its collection covers the area's history from the Bronze Age onward, anchored by objects of national importance: the Ballycroghan Swords, the Bangor Bell from the early Bangor Abbey settlement, and the Raven Maps, the only complete folio of Plantation-era maps in Ireland. Run by Ards and North Down Borough Council, it has long been one of Northern Ireland's most visited local museums and is free to enter.
