The Thermae Sylla Spa Wellness Hotel is considered unique for a number of compelling reasons, primarily centered on its ancient thermal springs, historical legacy, and commitment to holistic, medically-guided wellness.
The Ancient and Potent Thermal Springs
The hotel’s most unique feature is its location, built directly atop a natural thermal spring in Edipsos, Evia.
Natural Source: The water gushes from the earth at a high temperature (80–85°C) and is exceptionally rich in beneficial minerals, including calcium, magnesium, potassium, sodium, and the therapeutic element, radon.
Healing Heritage: The thermal springs of Edipsos have been renowned for their therapeutic and healing properties for over 2,300 years, with historical references by ancient Greek philosophers like Aristotle and Plutarch. The hotel is named after the Roman General Sulla, who supposedly sought healing for his arthritis in these very waters.
Unique Pools: The hotel’s pools are directly fed by this source. The indoor pool contains 100% medicinal water, while the spectacular outdoor pool features a unique blend of 50% thermal water and 50% purified seawater, offering a different therapeutic experience.
Rich History and Timeless Elegance
Established in 1897, the hotel itself is a historic, neo-classical landmark that embodies old-world charm and Belle Époque elegance.
Historical Guests: It has been a retreat for historical figures and celebrities, lending it a legendary status. Past guests include Winston Churchill, Maria Callas, and Aristotle Onassis.
Venerable Institution: It is recognized as one of Greece’s most historical medical spa resorts, blending its deep traditional roots with a luxurious 5-star experience.
Acclaimed Status and Medical Focus
The Thermae Sylla is not simply a luxury hotel; it is an internationally recognized destination for medical and thermal wellness.
World-Class Recognition: It has been ranked as one of the “World’s Top 10 Thermal Spas” by Conde Nast Traveler magazine.
Holistic & Medical Spa: The resort takes a scientific approach to spa therapies, offering specialized wellness and medical spa treatments.
