Hadrian's Arch, also known as the Triumphal Arch of Hadrian, is an ancient architectural marvel located in Jerash, Jordan. It was erected to commemorate the visit of Emperor Hadrian to the city in 129-130 AD. This impressive arch was once part of the wall that surrounded Jerash but now stands as an isolated monument. Standing 11 meters high, the arch features three arched openings – the central one being the largest and used for vehicular traffic, with the smaller side arches for pedestrians. The design reflects the grandeur of Roman architecture, adorned with columns and intricate carvings. Historically, Jerash is one of the best-preserved Roman provincial towns in the world, with Hadrian's Arch being one of its most noted landmarks. The area around Hadrian's Arch has been excavated and restored, revealing paved streets with colonnades, hilltop temples, theatres, spacious public squares, baths, fountains, and city walls pierced by towers and gates.
