The most basic mosque would be a prayer room with a wall marked with a "mihrab"—a niche designating the direction of Mecca that Muslims should face when praying. A traditional mosque will also have a minaret, a dome, and a space to wash before prayer. These elements help Muslims orient themselves within the world and remind them of the importance of prayer. In addition to helping Muslims find their way in life, the layout of a mosque makes it easier for worshippers to pray. The mihrab points toward Mecca, so Muslims know where they should face during prayers. In a large mosque, there may be separate rooms for men and women, which helps segregation during prayer. And since washing is required before prayer, the location of the bathroom near the mosque entrance makes sense. Mosques are important structures that play an integral role in defining Islamic identity. They can be found in almost every city across the globe—some old, others new. Some mosques were built following local traditions while others were designed by renowned architects. No two mosques are the same, which means that there is no single style or design that defines a "true" mosque. However, they all share common features such as the mihrab and the minaret, which help worshippers navigate around the room and locate the right place during prayer.
