Qubba

A qubba قُبَّة or (قُبَّات pl. qubbāt, qubbat), variants including ḳubba, kubbet and koubba, is an Arabic tomb, particularly the domed shrines of Islamic saints.

It originally meant a tent of hides, but it may also be used generally for tomb sites if they are places of pilgrimage.

It can also be used for the dome of the tomb or as a word for any dome, such as the Dome of the Rock (Arabic: قُبَّةُ ٱلْصَّخْرَة [Qubbatu 'ṣ-Ṣakhrah] Qubbat al-Sakhrah, Hebrew: כיפת הסלע Kippat ha-Sela).
