The 50 Best Hotel Openings of 2025

Portrush Adelphi, a Marine & Lawn hotel, Northern Ireland

Keys: 34
Design: AJ Capital Partners in-house team and CDA Group Architects
Why we love it: Channeling Northern Ireland’s heritage, the richly layered retreat evokes the region’s dramatic landscape through details like tartan upholstery and jewel-toned guestrooms. Meanwhile, in the elegant Red Sail room, Portrush’s maritime beauty comes alive via oil paintings of the coastline.
