It appears that Eilat Mazar’s Jerusalem excavation is turning up more significant finds every year (see here for previous discoveries). The Jerusalem Post has an article in which it is claimed that a wall from the First Temple period was recently uncovered in Jerusalem’s City of David. Here is an excerpt:
A 20-meter-long section of the 7-meter-thick wall has now been uncovered. It indicates that the City of David once served as a major government center, Mazar said.
Mazar estimates less than a quarter of the entire wall has been uncovered so far, and says that it is the largest site from King David’s time ever to have been discovered.
