« Hadrian, hero founder of the city. »— Inscription on Hadrian's Arch, 131 AD
Your quest begins at the Panathenaic Stadium, or Kallimarmaro, a historical monument built in 330 BC by Lykourgos for the Great Panathenaic Games. Restored in marble in 144 AD by Herodes Atticus, this 50,000-spectator site, with its 204.07 m track, hosted the Olympic Games in 1896 and 2004. Ancient Olympic races took place here, a direct link to the myth of Pheidippides and his legendary challenge. The stadium stands as a symbol of Athenian perseverance, an ideal starting point for exploring the heritage of Attica.
Heading towards the ancient heart of Athens, you pass by the Temple of Olympian Zeus, or Naos tou Olympiou Dios. Initiated around 520 BC under Pisistratus and completed in 131 AD by Emperor Hadrian, this colossal structure featured 104 Doric columns, 17 m high. Dedicated to Olympian Zeus, it was the largest temple in ancient Greece, with a surface area of 130.5 m x 68.5 m. Hadrian was honored here as the mythical founder of Athens, a testament to Roman grandeur in the Greek city. This archaeological site of the Olympieion is a reminder of the power of empires.
Just 300 m from the Panathenaic Stadium, Hadrian's Arch stands proudly. Erected in 131 AD, it marked the boundary between ancient Athens and the new city under Hadrian's influence. 18 m high, it bears two levels of inscriptions: 'Hadrian, hero founder of the city' to the north, and 'Athens, queen and mistress of the Greek world' to the south. This monument, located on the route to the ancient center, symbolizes the transition and fusion of Greek and Roman cultures. It testifies to the emperor's importance for the development of Athens.
Your journey then leads you to the Hill of the Areopagus, the Areios Pagos, the site of the Athenian supreme court from the 5th century BC and the location of Paul of Tarsus's trial in 52 AD. This 115 m hill, with its remains of rock-cut steps, offers breathtaking views of the Acropolis of Athens. A UNESCO site since 1987, the Acropolis, with the Parthenon built between 447 and 432 BC by Ictinos and Callicrates under Pericles, is a highlight of your journey, 1.2 km from the Stadium. Hadrian's Library, inaugurated in 132 AD and housing 100,000 volumes, completes this exploration of knowledge and justice, located 1 km from the Stadium and accessible on foot.
By walking through these sites, from the UNESCO Acropolis 1987 to the Kallimarmaro Stadium, you have retraced the steps of history and felt the power of Athens. This thematic circuit has allowed you to understand how figures like Herodes Atticus or Hadrian shaped Greece's world heritage. Every monument, every stone of Athens, from Hadrian's Arch to the Areopagus, has revealed a part of Pheidippides' lost challenge, offering you a unique interactive visit and a deep understanding of this millennial city.
