Newcastle, County Down – Seaside Activity Resort at the Foot of the Mournes

📍 Newcastle, Down

🏛️ Attraction

Last updated: 28 April 2026

Overview

Newcastle sits on the A2 coastal road on the Irish Sea, about 30 miles south of Belfast and a short drive from Newry, Rostrevor and Downpatrick. With a resident population of roughly 8 000, the town swells in summer as visitors flock to its golden beach, award‑winning promenade, bustling harbour and the dramatic foothills of the Mourne Mountains. The compact centre is easy to explore on foot, yet it offers a surprising range of activities – from world‑class golf to international air‑shows.


History & Background

The name Newcastle derives from a stronghold erected in 1588 by Felix Magennis (also recorded as MacGinnis) at the mouth of the Shimna River. The castle was demolished in 1830, leaving only a stone‑inscribed date as a reminder. The settlement grew from a modest fishing village into a Victorian‑era seaside resort, thanks in part to the Annesley family who opened St John’s Church (1832) and the Annesley Arms Hotel within the old castle grounds.

A tragic gale on 13 January 1843 claimed 73 fishermen from Newcastle and nearby Annalong. Public subscription funded Widows’ Row, a terrace of twelve cottages for the bereaved families – a poignant reminder that still features in local song. The town later embraced aviation; Harry Ferguson’s prize‑winning powered flight along the strand in 1910 is commemorated by a plaque, and the annual Festival of Flight airshow (since 2010) now draws up to 100 000 spectators.
