1. Birthplace of Hippocrates, the Father of Medicine

2. Home to One of Greece's Oldest Healing Centers: The Asclepeion
The Asclepeion is one of Greece's most important ancient healing centers, dedicated to Asclepius, the god of medicine. Built on a hill overlooking Kos and the sea, this sanctuary attracted patients from across the ancient world seeking treatment and healing. Visitors today can explore the ruins, which include temples, healing rooms, and thermal baths, all arranged across multiple terraces with panoramic views.
3. Natural Hot Springs at Therma Beach
Kos has natural hot springs, the most popular being Therma Beach on the eastern coast.
