Dome of the Rock, a mosaic

The Dome of the Rock (Arabic: قبة الصخرة, translit.: Qubbat As-Sakhrah, Hebrew: כיפת הסלע, translit.: Kipat Hasela, Turkish: Kubbetüs Sahra) is a notable Islamic shrine[1] for pilgrimage[2] in what Muslims call masjid al-Aqsa or the Noble Sanctuary (al-Haram al-Qudsi al-Sharif, Arabic: الحرم القدسي الشريف) — which Jews and Christians call Har ha-Bayit (Hebrew: הר הבית) or the Temple Mount — it remains one of the best known landmarks of Jerusalem. It was built between 687 and 691 by the 9th Caliph, Abd al-Malik. It is often mistakingly[3] referred to as Mosque of Umar, the actual mosque of Caliph Umar ibn al-Khattab residing next to the Church of the Holy Sepulchre.
