Prayer is one of the five pillars of Islam. Therefore, mosques are centers of religious life. There are neighborhood mosques, usually kept simple, Friday mosque and festive mosques, mostly located outside the city.
Often the mosque has an enclosed space – the Winter Mosque, and an open space – the Summer Mosque, which is mostly integrated into the courtyard.
The main room of the mosque with the prayer niche (mihrab) usually has a dome. The main room has an entrance portal (Pichtak). There are pillared arcades around the courtyard.
