Constructed during the fourth century AD, this church stands as one of the most ancient in the historic city of Jerash. It was built atop the remains of the Roman Temple of Dionysus. Notably, some of the architectural components, such as columns and adornments, were taken from the Temple of Zeus and reutilized into the cathedral's construction.
The wonderful architecture of the Cathedral is still apparent in what remains today. The main entrance to the church is on the west side, from an atrium called the Fountain Courtyard.
Eight other entrances also allowed access to the church and inside the space is partitioned into three sections by two rows of columns with an apse at the front of the church that only the priest would have access to. Note the holes in the columns and walls, which may have been for attaching decorative plaster panels and bronze embellishments.
