"Underground Roman Baths in NYC Part Roman bath, part Turkish hammam, part massage parlor—it all adds up to a restorative haven in the concrete jungle that is Manhattan. Aire is part of a chain that started in Seville, Spain, and every location is specially chosen to include an underground bath area comprised of stone and marble pools, treatment rooms, a hammam, and relaxation areas. The Tribeca building dates to 1883; all original architectural elements were restored and garnished with lanterns from Morocco plus marble from Spain. Old wood beams that could have been thrown away during construction were turned into beautiful benches and tables, and candles are the only source of light in most of the 16,000 square-foot space. A salt pool allows you to experience what many travel all the way to the Dead Sea for: effortless flotation. The Eucalyptus-scented hammam cleared out my head so I could leave with renewed vigor for the day's writing projects. My massage, too, was worth every penny, though you can use the pools and steam room without being treated by a masseuse. And extendd hours (from 9 a.m. to 11 p.m. daily) mean you can drop in even after a full day of work or sightseeing."
