The Arch of Hadrian is an ancient Roman structure in Jerash, Jordan.
It is an 11-metre high triple-arched gateway erected to honor the visit of Roman Emperor Hadrian to the city (then called Gerasa) in the winter of 129–130.
The Arch's relative remoteness from the city walls points to a plan for southward expansion of Gerasa during its heyday.
[4] There are three vaulted passageways on the lower level and each of these is flanked by two columns with Corinthian capitals.
Each niche is on top of a small entablature, which stands on two pilasters crowned with capitals.
