Thermae Sylla, One of the World’s Top 10 Spas

Thermae Sylla Spa and Wellness Hotel is one of the world’s leading thermal spa facilities. Located at Aidipsos, a coastal town on Greece’s second-largest island, Evia, it’s a 2.5-hour drive from Athens, or a short ferry ride away. 

Famous for its healing properties since the 4th Century, the coastal spa town boasts more than 80 natural thermal springs with water flowing from natural wells. Thermae Sylla, voted one of the top 10 spas in the world, is built over these natural thermal springs with outstanding healing properties.

History of Aidipsos 

Since antiquity, Aidipsos is well-known for its thermal springs that help heal, relax and rejuvenate the body, mind, and soul. Ancient Greek philosophers Hippocrates (father of medicine) and Aristotle visited the springs and wrote about the huge benefits and the rare microclimate they create. Since then, Aidipsos has drawn people from all around the world, who come here to experience this wellbeing retreat. 

The hotel 

Beautifully designed by Erricos Tobazis, Thermae Sylla features neoclassical architecture with hints of Art Nouveau. The grand building, which opened its doors in 1896, is constructed of local stone from Evia and during the construction process, ruins of a Roman spa were discovered. Over the years, the hotel has welcomed famous guests including Greta Garbo, Omar Sharif, Winston Churchill, Aristotle Onassis and Maria Callas. 

Therapeutic waters of Aidipsos

Thermae Sylla has one of the most therapeutic spa waters in the world, with thermal springs which flow from a depth of 3,000 metres at a temperature of 75º C to 85º C. The water under the property is particularly rich with different metals and elements; including traces of Radon. The waters also contain calcium, magnesium, sodium, potassium and sulfate, as well as manganese, iron, and strontium.
