Some minor quarrying occurred in 1907 when stone was obtained to be used in the Ottoman clock tower over the Jaffa Gate.[7] Otherwise, the site was not frequented again until the 1920s, when it began to be something of a tourist attraction. In the late 20th century, the East Jerusalem Development Corporation carried out restorations of the cave. In the mid-1980s, The Jerusalem Foundation built paths and installed lights throughout the cavern, facilitating tourist access.
