On July 25, 2010, a Ner Tamid, an oil-burning "eternal light," was installed within the prayer hall within Wilson's Arch, the first eternal light installed in the area of the Western Wall. According to the Western Wall Heritage Foundation, requests had been made for many years that "an olive oil lamp be placed in the prayer hall of the Western Wall Plaza, as is the custom in Jewish synagogues, to represent the menorah of the Temple in Jerusalem as well as the continuously burning fire on the altar of burnt offerings in front of the Temple," especially in the closest place to those ancient flames.
