This arch was built in the honour of Emperor Hadrian's visit to Gerasa during 129 AD. This impressive triple-bay monument is one of the largest known arches of the Roman Empire. It was also ornately decorated with acanthus leaves. A magnificent Greek inscription adorned the north facade looking towards the city. Today the arch is known as "Bab Amman" which means "Amman Gate" in Arabic, as it stood on the road towards Philadelphia (Amman). It has been restored to give a closer impression of the grandeur it once imposed.
