What is hadrian arch?

The Hadrian's Arch is a monumental gateway in Athens, Greece, located in the historic district of Athens, near the Temple of Olympian Zeus. It was erected in honor of the Roman Emperor Hadrian in 131 AD. The arch is constructed of Pentelic marble and stands approximately 18 meters high, 13.5 meters wide, and 2.3 meters deep.

The arch has three openings: a central arch flanked by two smaller ones. The central arch spans 9 meters in width and 12 meters in height, and is embellished with decorative reliefs depicting the life of Hadrian and his achievements. The reliefs also portray scenes from Athenian myth and history, including the Battle of Marathon and the founding of Athens.

The Hadrian's Arch served as a ceremonial gateway, marking the entrance to the city of Athens for travelers arriving from the east via the Roman Road. Over the centuries, the arch has been damaged by earthquakes and other natural disasters, but it has been restored and preserved. Today, it is one of the most popular tourist attractions in Athens and a symbol of the city's rich history and culture.
