The springs of Thermopylae are 15 km from the city of Lamia. The area is familiar to us from the Battle of Thermopylae between Greeks and Persians in 480 BC. Next to the road is the statue of Leonidas and the holy hill, where Leonidas went down fighting with the 300 Spartans and the 700 Thespians. According to mythology, Hephaestus, at the request of the goddess Athena, created the springs so that Hercules can wash and recuperate after his labours. The organization of the sources began in 1935. The temperature of the water is 40oC. It is indicated for the treatment of rheumatic, gynecological diseases and disorders of the peripheral nervous system.
