The Western Wall is also known as the Wailing Wall and in Islam as the Buraq Wall.
It is a portion of ancient limestone wall in the Old City of Jerusalem that forms part of the larger retaining wall of the hill known to Jews and Christians as the Temple Mount.
Just over half the wall's total height, including its 17 courses located below street level, dates from the end of the Second Temple period, and is believed to have been begun by Herod the Great.
