Mihrab
Niche in a mosque indicating the direction of prayer
Mihrab (Arabic: محراب, miḥrāb, pl. محاريب maḥārīb) is a niche in the wall of a mosque that indicates the qibla, the direction of the Kaaba in Mecca towards which Muslims should face when praying. The wall in which a mihrab appears is thus the "qibla wall".
