What is a Mihrab in Islamic architecture?

The correct answer highlights that a Mihrab is a niche in a mosque that indicates the direction of Mecca, which is essential for Muslim prayer. This architectural feature serves a significant religious function, as Muslims are required to face Mecca during their five daily prayers. The Mihrab is often elaborately decorated and can vary in size and design depending on the mosque, but its primary purpose remains a vital aspect of Islamic worship. It not only guides worshippers in their orientation toward Mecca but also signifies a sacred space within the mosque, further emphasizing its importance in Islamic architecture and practice.
