Excavations by J. B. Hennessy revealed a Late-Bronze (1550-1200 b.c.) temple. Remains exist from the Roman period on the citadel above Philadelphia (the name of the city in the Roman times) and in the city below. These include a beautifully preserved, six-thousand-seat theater, a smaller odeum (music hall), and a nymphaeum. These all date to the second century a.d. The principal remains are on Citadel Hill, which contained all the public buildings, temples, churches, etc.
