Thermae Sylla Spa Wellness Hotel in Edipsos (Aidipsos) on the island of Euboea is Greece's most prestigious and historically distinguished thermal hotel, a magnificent neoclassical building rising directly from the sea front of one of the oldest continuously used thermal resorts in the ancient world — Aristotle described the Edipsos springs, Roman general Sulla bathed here after his campaigns, and the emperor Hadrian developed the facilities. The sulphurous waters, which emerge at up to 82°C and flow directly into the hotel's seafront pools where they mix with Aegean seawater, provide one of the most dramatically atmospheric bathing experiences in Greece. The hotel's neoclassical architecture, grand colonnaded facade and historical guest list — including Maria Callas, Winston Churchill and Aristotle Onassis — give it an aura of aristocratic Mediterranean elegance. The ferry crossing from the mainland port of Arkitsa adds a pleasingly maritime dimension to the journey.
