The decumanus maximus continues west of the main site for 1km or so, leading to some ruins of limited interest, including baths, mausoleums and gates. Japanese and Iraqi archaeologists are currently excavating here. Most interesting is the basilica built above one of the Roman mausoleums. You can peer into the subterranean tomb through a hole in the basilica floor. The sarcophagus of Helladis that once lay here can be seen in the Museum of Anthropology & Archaeology in Irbid.
