Western Wall (Old City, Jerusalem) – known as the Wailing Wall to followers of Judaism, these were the last remnants of the Temple in Jerusalem. The Western Wall was part of the most magnificent structure Jerusalem had ever seen. It was one of four walls Herod the Great built to support the plaza on which the Temple stood. It was almost 1,500 ft. long – the rest can still be seen inside the Western Wall Tunnel. Originally, it was some 90 ft. high, and reached some 60 ft. into the ground.
Tourists who are not claustrophobic can tour the series of tunnels that run under the Western Wall. Excavations do down 15 meters – all the way down to the foundation stones of the Western Wall. Such tunnels run through the city’s Muslim Quarter. Among the archaeological sites found that is a Second Temple mikveh (a Jewish ritual bath – most likely used 2,000 years ago).
