Church terrace (notice on site) : During the Byzantine and Early Islamic periods two churches were built on a terrace which had been constructed on the western slope of the Acropolis during the second century AD. The churches replaced an earlier Roman public building, probably a colonnaded hall or a market basilica. During the first half of the 6th century AD a church consisting of square building with an octagonal interior was erected in the approximate centre of the terrace. To the west of the church an entrance hall (narthex) was added and to the north, a colonnaded courtyard (atrium). From the main street of the city three gates provided access to the terrace. To the south of the church a smaller, three-aisled basilica was built in the middle of the second half of the 6th century AD. The finds of four tombs and five reliquaries in the churches indicate the importance of the complex. Probably this was a site of pilgrimage, in which the tomb in the middle of the earlier church may have been the grave of a venerated martyr. Like the West Theatre and many other buildings in Gadara, the churches were destroyed by earthquakes in the middle of the 8th century.
I took pictures walking about, a bit randomly.
