The site cannot be identified with absolute certainty but this site is widely believed to be the site of Plato's Academy. The most famous school of European philosophy was in operation from 387 BC until it was closed by Justinian in A.D. 526, It remains a grove, with some remains of stone walls. Though a rather sad place in a poorly maintained public park, one can reflect that the philosophical ideas which shaped western gardens down to modern times were developed nearby.
