Emek Shaveh have recently posted a report and map on their web site describing the significant archeological excavations carried out in the tunnels and other underground spaces in the old city and its surrounding. The report includes a historical and current overview of the excavations, their influence on the conflict and on the residents of the old city, their importance and their aims.
Emek Shaveh is an organization of archaeologists and community activists focusing on the role of archaeology in Israeli society and in the Israeli-Palestinian conflict. One of their main focuses is the village of Silwan in East Jerusalem where the state of Israel gave an archaeological site to a group of militant settlers. The archaeology in this area is being abused by the settlers and the state to evict the Palestinian residents of the village from their houses, and to expand the settlement “Ir David” (the City of David).
I made the maps for the report that can be found here.
