Western Wall Tunnel
After the Six-Day War, excavations began to expose more of the Western Wall. The excavations lasted almost twenty years. They found many facts about the history and geography of the Temple Mount that had not been known. The excavations were difficult. Tunnels ran below neighborhoods that were built on top of structures from the Second Temple Period. The excavations were done with the supervision of scientific and rabbinic experts. This was to ensure both the stability of the structures and to prevent damaging the historic artifacts. In 1988, the Western Wall Heritage Foundation was formed. It took over the excavation, maintenance and renovations of the Western Wall and Western Wall Plaza.
