How may the Church of the Holy Sepulchre have influenced the Dome of the Rock’s design?

The Dome of the Rock was designed with a grand scale and lavish decoration that may have been intended to rival the Church of the Holy Sepulchre, a prominent Christian holy building in Jerusalem.1

Architecturally, the Dome of the Rock belongs to a class of Byzantine religious buildings known as martyria—polygonal or circular shrines typically used to commemorate events of special religious significance or to mark the graves of saints. Its design reflects an effort to establish Islam as the rightful successor to the Abrahamic tradition, and its construction served as a monumental statement of the Umayyad caliphate's presence in a city already adorned with significant Christian structures.1
