Iveagh Garden Hotel

Dublin, Ireland

Although Iveagh offers plenty of guest perks—a central location, views of lush surroundings—its greatest feature lies below the surface: the new hotel, housed in a 20th century bank building, has been retro­fitted to source all of its energy from an underground river. Manager John Pardy says the changes decreased their energy usage by 78%, making it one of the most sustainable hotels in Europe. —Samantha Cooney
