The Kallimarmaro, also known as the Panathenaic Stadium, is a symbolic monument of the heritage of the Olympic Games and sports in general. It hosted the first modern Olympic Games in 1896, embodying the spirit of culture, friendship, peace, and fair play. This world heritage site offers visitors a deep dive into the past and their historical memory.

Located for centuries (since 330 BC) in the center of the capital, at the foot of Mount Ardittos and next to the Zappeion, it was constructed by Lycurgus, a notable politician and orator of antiquity, responsible for the public works of ancient Athens. The stadium hosted the Great Panathenaic Games. Its form remained until the 2nd century AD, when significant renovations were carried out by the orator Herodes, son of Atticus.

Its new shape resembled a horseshoe, with propylaea built at the main entrance, and the seats were made of Pentelic marble, increasing its capacity to 50,000 spectators.
