1. Mosques contain a niche that marks the direction of Mecca.

Explanation:

A niche in the wall that points the direction of Mecca is part of every Mosque and it's called Mihrab.

As it is an important part, it is given special attention to the aspect of architecture. Mihrabs are heavily decorated with religious ornaments, geometric designs, and calligraphy, most likely stating Qur'an. They vary in size and appearance but are always included in the architecture of the mosque.

The secret place of Kaaba in Mecca is believed to be built by Abraham and Ishmael, and the direction pointing to it which mihrab points is called Qibla. When praying, Muslims should be turned to the point of the qibla, and so they use mihrabs to show them where to turn during the prayer.
