In case you didn't see it, check out this article about the threats to Leptis Magna in Libya. Emperor Septimius Severus was born in Leptis Magna and devoted great resources to the embellishment of the city until it rivalled Carthage and Alexandria. Or that was the plan.
During the reign of Septimius Severus, the ancient city of Ashkelon also underwent signficant architectural embellishment. It is believed the odeon we are currently excavating was built during his reign.
Now, to the picture. The picture I posted an eon and a day ago is of some of the destroyed medieval fortifications in the vicinity of the Jerusalem Gate. This is the area where the team from Hebrew University worked during the 2011 field season.
