The Oval Square is a famous building in the ancient ruins of Jerash in Jordan. It is located at the beginning of the Colonnade Street and was built in the first century AD. The square is an asymmetrical stone-paved open space, 90 meters long and 80 meters wide, used for major gatherings. Two rows of nearly 10-meter-high Roman columns are arranged on both sides, making it more imposing and expanding the visual space from all angles. There is a broken column in the center of the square, which may be the remains of some landmark.
