The topography of the site was made up of three ridges, meshed with the idea of establishing three clusters of buildings – the government precinct, a university campus and a museum.
[10] The first salvage excavation was conducted before Binyanei HaUma was built, in July- August 1949, by M. Avi-Yonah, who unearthed hewn installations, cisterns and pools of various sizes dating to the Herodian period, bricks and tiles bearing stamps of the Tenth Roman Legion, and the remains of a monastery.
The area had been covered by a thick layer of plaster upon which were found large mortaria and many bricks, some bearing stamps of the Tenth Legion.
During the work on a new international convention center east of Binyanei HaUma, a large salvage excavation was conducted in April–September 1992 on behalf of the Israel Antiquities Authority, but roughly 60% of the parking lot area had already been dug up by bulldozers.
In July 1993, a small excavation in the northwestern corner dismantled kilns of the Tenth Legion and lifted a mosaic floor of the Byzantine period.
