The plane tree of Hippocrates stands between the entrance of the Castle of Neratzia and the Gazzi Hassan mosque.
According to the legend, Hippocrates used to teach his students under the shade of the tree. The tree that stands now it is said to be a descendant of the original tree that stood there during the times of Hippocrates (460BC – 370BC) and it is about 500 years old.
The perimeter of the tree is about 10m and after the years it has been hollowed and turned out to look like a cave.
Next to the Plane tree there are two fountains builded by the Ottoman Governor Gazzi Hassan with an Arabic inscription that supports that there was a spring with fresh water coming out.
