The tree is located directly in front of the entrance to the Knights Hospitaller castle (Neratzia Castle).
Local tradition claims Hippocrates taught his students medicine under the original tree's canopy.
The current tree is a Platanus orientalis, a species known for its longevity and ability to grow to massive proportions.
Metal scaffolding supports the decaying branches to prevent them from collapsing under their own weight.
The site acts as a centerpiece for the town square, surrounded by stone fountains and remnants of historical architectural layers.
Botanical evidence confirms the tree is not thousands of years old, though it likely stands on the exact location of a predecessor.
The Hippocrates Plane Tree is a massive Oriental plane tree (Platanus orientalis) situated in the center of Kos Town, Greece, traditionally associated with the physician Hippocrates. Botanists estimate the current tree's age at approximately 500 to 600 years, suggesting it is a descendant or successor of an original tree that stood on the site over 2,400 years ago. The tree is supported by a system of scaffolding and pillars due to its significant girth, which measures over 12 meters in circumference. It stands adjacent to the Neratzia Castle, which was constructed by the Knights Hospitaller during the 14th century. The site remains a focal point of local historical lore and is maintained as a protected natural monument within the urban fabric of Kos. The surrounding area features Ottoman-era architecture, including the Gazi Hassan Pasha Mosque.

Visit during the early morning to avoid large groups from cruise ships.
Combine your visit with a walk through the nearby Knights Hospitaller castle grounds.
Look for the Ottoman-style fountain located nearby, which is integrated into the site's historical context.
Do not attempt to climb or lean heavily on the protective scaffolding or the tree itself.
