Belle Spa & Wellness at THE PLAZA Seoul, part of the Autograph Collection, is an elegant oriental spa retreat located on the 15th floor of the hotel's annex in the heart of downtown Seoul, just steps from City Hall. The spa embraces a holistic philosophy centred on life management, creating an atmosphere of deep rest and renewal through the use of natural materials — wood, stone, and live plants — alongside panoramic views of the cityscape. Signature treatments include the Bronze Aroma Treatment, which combines traditional Korean bronze utensils with 100% natural aromas for full-body therapy, as well as deep tissue massages, aroma stone therapy, and luxury facial programs featuring the French brand Biologique Recherche. A sauna, hot tub, pool, and a rooftop garden complete this refined urban wellness sanctuary.
