Minaret (/ˌmɪnəˈrɛt, ˈmɪnəˌrɛt/; Persian: مناره menare, Azerbaijani: minarə, Turkish: minare,), from Arabic: منارة manāra, lit. "lighthouse", also known as Goldaste (Persian: گلدسته), is a distinctive architectural structure akin to a tower and typically found adjacent to mosques. Generally a tall spire with a conical or onion-shaped crown, usually either free-standing or taller than associated support structure. The basic form of a minaret includes a base, shaft, and gallery. Styles vary regionally and by period. Minarets provide a visual focal point and are traditionally used for the Muslim call to prayer (Adhan).
The purpose of minarets in traditional Eastern region architecture is to serve as a ventilation system for a building in very hot climates. Usually, the building would consist of a tower with large open windows that would allow for cold air to enter, and a dome in the center of the building that would (hypothetically) have an opening in the ceiling that would both accumulate and allow warm air to leave the building through a cupola. That buildings of middle eastern origins have such outstanding features is architecturally intentional. Mosques usually have a center hall room with a raised ceiling or dome to allow for heat to accumulate and rise upwards leaving the cold air on the lower floor allowing for a system of natural air conditioning.
However, in modern times, with the invention of the modern air conditioners, the purpose of minarets has changed to traditional symbol. The minaret would be equipped with a speaker that would call people to prayers in Muslim countries. In addition to providing a visual cue to a Muslim community, the main function at present is to provide a vantage point from which the call to prayer, or adhan, is made. The call to prayer is issued five times each day: dawn, noon, mid-afternoon, sunset, and night. In most modern mosques, the adhān is called from the musallah (prayer hall) via microphone to a speaker system on the minaret.
The earliest Mosques lacked Minarets, and the call to prayer was performed elsewhere; hadiths relay that the Muslim community of Medina gave the call to prayer from the roof of the house of Muhammad, which doubled as a place for prayer. Around 80 years after Muhammad's death, the first known minarets appeared.
The Minarets had various forms (in general round, squared, spiral or octagonal) in function of the infrastructure of each architecture.
The number of Minarets by Mosques was not fixed: at origin, one Minaret would accompany each Mosque, then the builder would reconstruct several. The reasons for that mainly revolve around esthetics, symmetry, the will to punctuate a strong architectural feature, as well as assure the stability of the design.
Since a long time ago, the Great Mosque of Mecca (Sacred Mosque) of Mecca would be the only to have six Minarets. However, when the Ottomans built the Blue Mosque of Istanbul, they included six Minarets. A seventh Minaret has to be constructed in Mecca, in order for the Sacred Mosque not to be surpassed. However calling for prayer is usually done from one Minaret.
In the Maghreb, the oldest Minaret is that of the Great Mosque of Kairouan in Tunisia. The oldest Minaret still standing of all the Muslim world and consequently the oldest in the world. The construction of the Great Mosque of Kairouan, probably commenced at the beginning of the 8th century, date of its actual state of the first half (9th century, towards 836) according to the opinion of most archeologists. Constituted by three levels of decreasing widths reaching sizes of 31.5 meters, and being distinguished by an aspect both massif and majestic, this Great Mosque is considered as the prototype of Minarets in the Western Muslim World.
History has also equally provoked the destination change of places of worship, and notably around the Mediterranean. Accordingly, when a Church was transformed into a Mosque, the Bell Tower was transformed into a Minaret, similarly when the former Cathedral, became the Almohad Mosque, in Seville, became again the Seville Cathedral, the Minaret of Giralda became a Bell Tower. This was a typical style transformation of a place of worship.
The tallest minaret, at 210 metres (689 ft) is located at the Hassan II Mosque in Casablanca, Morocco. In some of the oldest mosques, such as the Great Mosque of Damascus, minarets originally served as illuminated watchtowers (hence the derivation of the word from the Arabic nur, meaning "light").
The basic form of minarets consists of three parts: a base, shaft, and a gallery. For the base, the ground is excavated until a hard foundation is reached. Gravel and other supporting materials may be used as a foundation; it is unusual for the minaret to be built directly upon ground-level soil. Minarets may be conical (tapering), square, cylindrical, or polygonal (faceted). Stairs circle the shaft in a counter-clockwise fashion, providing necessary structural support to the highly elongated shaft. The gallery is a balcony that encircles the upper sections from which the muezzin may give the call to prayer. It is covered by a roof-like canopy and adorned with ornamentation, such as decorative brick and tile work, cornices, arches and inscriptions, with the transition from the shaft to the gallery typically sporting muqarnas.
Styles and architecture can vary widely according to region and time period. Here are a few styles and the localities from which they derive:
