Constructed in 131 A.D. by the Roman Emperor Hadrian, as part of a wall separating the old and new cities of Athens. The 18 meter HADRIAN'S ARCHwas made of marble from nearby Mount Pentelikon and decorated in the Corinthean order.
You will find Hadrian's Arch at Amalias Avenue at the entrance of the site of the Temple of Olympian Zeus, just south of the National Gardens.
It was constructed by the Athenians in 131 AD, in honor of the Roman emperor Hadrian. The arch is crowned by a series of corinthian columns. The whole monument (as the Parthenon of the Acropolis) is made of pentelic marble - Penteli is a mountain 25 km north of Athens.
Behind this monument, the temple of Olympian Zeus is clearly visible, both of them are near Zappeio.
The Arch of Hadrian
Fondest memory: Hadrian's Arch
The triumphal arch lies on an ancient street that led from the old city of Athens to the new, Roman section, built by Hadrian. It was constructed by the Athenians in A.D. 131, in honor of their benefactor emperor. Two inscriptions are carved on the architrave, one on each side: the first, on the side towards the Acropolis reads "This is Athens, the ancient city of Theseus"; the second, on the other side, facing the new city reads "This is the city of Hadrian and not of Theseus".
