what is the wall in a mosque called that is toward mecca
Mihrab Mihrab (Arabic: محراب‎‎ miḥrāb, pl. محاريب maḥārīb) is a semicircular niche in the wall of a mosque that indicates the qibla; that is, the direction of the Kaaba in Mecca and hence the direction that Muslims should face when praying. The wall in which a mihrab appears is thus the "qibla wall".
Walls of Jerusalem The Walls of Jerusalem (Arabic: أسوار القدس‎; Hebrew: חומות ירושלים‬) surround the Old City of Jerusalem (approx. 1 km²). In 1535, when Jerusalem was part of the Ottoman Empire, Sultan Suleiman I ordered the ruined city walls to be rebuilt. The work took some four years, between 1537 and 1541.[1][2]
