Nestled in the historic town of Mystras, once fought over by Franks, Venetians, Byzantines and Ottomans, and now a UNESCO World Heritage site, the Euphoria Spa pays tribute to its mystical surroundings and remnants from the Byzantium era. The fully-immersive retreat curates personalised programmes designed around the ancient Chinese and Hellenic world, for a unique spin on traditional remedies. The spa is built into the mountainside and rises over four levels, with memorable features including its elegant sphere pool.
