Dome of the Chain

Dome of the Chain (Arabic: قبة السلسلة, romanized: Qubbat al-Silsilah) is an Islamic free-standing domed building located adjacently east of the Dome of the Rock in the al-Aqsa Mosque compound in the Old City of Jerusalem. It is one of many small buildings that can be found scattered around the Al Aqsa Mosque . Its exact historical use and significance are under scholarly debate. Erected in 691–92 CE,^[1] the Dome of the Chain is one of the oldest surviving structures at the al-Aqsa Mosque compound.^[2]

It was built by the Umayyads, became a Christian chapel under the Crusaders, was restored as an Islamic prayer house by the Ayyubids, and has been renovated by the Mamluks, Ottomans and the Jordanian-based waqf.
