Confirming its status as Europe’s most booming capital, Dublin gains a world-class hotel in the new Four Seasons Hotel Dublin. The luxury brand, while providing every 21st-century convenience, also pays homage to the past. Lodged in the historic Ballsbridge district on The Royal Dublin Society grounds — home to the annual horse show — the tony hotel strikes a Georgian-Victorian pose via brick walls, slate roof, and lush inner courtyard. Its 259 rooms survey views from Dublin Bay to the Wicklow Mountains. And the 11,000-square-foot spa imports the Irish wilds inside with local spring water and Celtic treatments. Rooms from $315. 011-353-1-665-4000, www.fourseasons.com -
