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".
Mecca Mecca (/ˈmɛkə/) or Makkah (Arabic: مكة‎[1] Makkah (Hejazi pronunciation: [ˈmakːa,ˈmäkːä]) is a city in the Hejazi region of the Arabian Peninsula, and the plain of Tihamah in Saudi Arabia, and is also the capital and administrative headquarters of the Makkah Region.[8] The city is located 70 km (43 mi) inland from Jeddah in a narrow valley at a height of 277 m (909 ft) above sea level, and 340 kilometres (210 mi) south of Medina. Its resident population in 2012 was roughly 2 million, although visitors more than triple this number every year during the Ḥajj (Arabic: حَـجّ‎, "Pilgrimage") period held in the twelfth Muslim lunar month of Dhūl-Ḥijjah (Arabic: ذُو الْـحِـجَّـة‎).
