The Western Wall in Jerusalem - the Kotel
The Western Wall is the last remaining piece of the Ancient Temple in Jerusalem. It was an external wall lining the compound of the Holy Temple and along it ran a long road with a market selling sacramental artifacts and livestock to pilgrims to Jerusalem.
The Western Wall is holiest site in Judaism, and Jewish believers, as well as members of other faiths, flock to it daily in order to pray. There is also a tradition of placing notes in the cracks between the ancient stones, with people writing messages and requests to god.
The Western wall has been under control of the State of Israel since 1967, and members of all faiths are allowed in the site and permitted to visit the adjacent Temple Mount.
Below the Kotel, the Western Wall tunnels reveal lower layers of the wall, as well as numerous archaeological finds.
