A minaret (ˌmɪnəˈrɛt,_ˈmɪnəˌrɛt; منارة, or مِئْذَنة; minare; گلدسته) is a type of tower typically built into or adjacent to mosques. Minarets are generally used to project the Muslim call to prayer (adhan), but they also served as landmarks and symbols of Islam's presence. They can have a variety of forms, from thick, squat towers to soaring, pencil-thin spires. Two Arabic words are used to denote the minaret tower: manāra and manār. The English word "minaret" originates from the former, via the Turkish version (minare). The Arabic word manāra (plural: manārāt) originally meant a "lamp stand", a cognate of Hebrew menorah. It is assumed to be a derivation of an older reconstructed form, manwara. The other word, manār (plural: manā'ir or manāyir), means "a place of light". Both words derive from the Arabic root n-w-r, which has a meaning related to "light". Both words also had other meanings attested during the early Islamic period: manār could also mean a "sign" or "mark" (to show one where to go) and both manār and manāra could mean "lighthouse". The formal function of a minaret is to provide a vantage point from which the muezzin can issue the call to prayer, or adhan. The call to prayer is issued five times each day: dawn, noon, mid-afternoon, sunset, and night. In most modern mosques, the is called from the (prayer hall) via microphone to a speaker system on the minaret. Additionally, minarets historically served a visual symbolic purpose. In the early 9th century, the first minarets were placed opposite the qibla wall. Oftentimes, this placement was not beneficial in reaching the community for the call to prayer. They served as a reminder that the region was Islamic and helped to distinguish mosques from the surrounding architecture. They also acted as symbols of the political and religious authority of the Muslim rulers who built them. The region's socio-cultural context have influenced the shape, size and form of minarets. Different regions and periods developed different styles of minarets.
