A mosque is a place of worship for followers of Islam. The primary purpose of the mosque is to serve as a place where Muslims can come together for prayer and some other activities of their life (i.e, a centre for information, education, and dispute settlement). The Imam leads the prayer. Nevertheless, mosques are known around the world nowadays for their general importance to the Muslim community as well as their demonstration of Islamic architecture. Today, most mosques have elaborate domes, minarets, and prayer halls. Mosques originated on the Arabian Peninsula, but now exist on all the world's inhabited continents. They are not only places for worship and prayer, but also places to learn about Islam and meet fellow believers.
