The Asclepion was built over three landscaped terraces, each having a different function.
Containing a propylon (entrance), with 24 steps and 4 columns, the first level housed a number of treatment and consultation rooms, as well as fountains (for ritual therapies) and Roman-era baths. It’s not certain, but it is believed that the medical school was on this level.
A marble staircase takes you up to the next terrace, notable for its temples. The remains of the 4th century BC Temple of Asclepius are the oldest in the sanctuary, and seven columns of the Temple of Apollo (father of Asclepius) have been restored to help bring the site back to life.
A 60-step staircase takes you to the remains of the largest temple, dedicated to Asclepius. To each side was a Doric portico (stoa), with rooms for visitors and patients. There are also the remains of an early-Christian church dedicated to Panagia Tarsou. From here, there’s a further staircase leading to a forest of cypress and pine trees dedicated to Apollo, from where you get a view all the way to the sea.
Hippocrates’ Plane Tree
You can’t visit Kos without seeking out Hippocrates’ iconic Plane Tree, under which he taught some 24 centuries ago. Located opposite the Neratzia Fortress, next to the ancient Αgora of Kos, the tree is 4.7m in diameter and covers an area of over 12m squared.
The Hippocrates Foundation Museum & Botanical Gardens
Around half a kilometre east is the International Hippocratic Foundation of Kos, built where Hippocrates is believed to have been born. There’s a museum with a wealth of knowledge about Hippocratic medicine and botanical gardens with more than 100 therapeutic plants and herbs once cultivated by the great man.
