Mosque

A mosque, also called masjid, is a place of prayer for Muslims. Mosques are usually covered buildings, but can be any place where prayers are performed, including outdoor courtyards. The first mosques were simple places of prayer for Muslims, and may have been open spaces rather than buildings.

From Indonesia to the United Kingdom, the mosque in its many forms is the quintessential Islamic building. The mosque, masjid in Arabic, is the Muslim gathering place for prayer. Masjid simply means “place of prostration.” Though most of the five daily prayers prescribed in Islam can take place anywhere, all men are required to gather together at the mosque for the Friday noon prayer

Mosques are also used throughout the week for prayer, study, or simply as a place for rest and reflection. The main mosque of a city, used for the Friday communal prayer, is called a jami masjid, literally meaning “Friday mosque,” but it is also sometimes called a congregational mosque in English. The style, layout, and decoration of a mosque can tell us a lot about Islam in general, but also about the period and region in which the mosque was constructed.

The home of the Prophet Muhammad is considered the first mosque. His house, in Medina in modern-day Saudi Arabia, was a typical 7th-century Arabian style house, with a large courtyard surrounded by long rooms supported by columns. This style of mosque came to be known as a hypostyle mosque, meaning “many columns.” Most mosques built in Arab lands utilized this style for centuries.

Common features

The architecture of a mosque is shaped most strongly by the regional traditions of the time and place where it was built. As a result, style, layout, and decoration can vary greatly. Nevertheless, because of the common function of the mosque as a place of congregational prayer, certain architectural features appear in mosques all over the world.

Sahn (courtyard)

The most fundamental necessity of congregational mosque architecture is that it be able to hold the entire male population of a city or town (women are welcome to attend Friday prayers, but not required to do so). To that end congregational mosques must have a large prayer hall. In many mosques this is adjoined to an open courtyard, called a sahn. Within the courtyard one often finds a fountain, its waters both a welcome respite in hot lands, and important for the ablutions (ritual cleansing) done before prayer.

Mihrab (niche)

Another essential element of a mosque’s architecture is a mihrab—a niche in the wall that indicates the direction of Mecca, towards which all Muslims pray. Mecca is the city in which the Prophet Muhammad was born, and the home of the most important Islamic site, the Kaaba. The direction of Mecca is called the qibla, and so the wall in which the mihrab is set is called the qibla wall. No matter where a mosque is, its mihrab indicates the direction of Mecca (or as near that direction as science and geography were able to place it). Therefore, a mihrab in India will be to the west, while a one in Egypt will be to the east. A mihrab is usually a relatively shallow niche, as in the example from Istanbul, above left. In the example from Spain, shown above right, the mihrab’s niche takes the form of a small room, this is more rare.

Minaret (tower)

One of the most visible aspects of mosque architecture is the minaret, a tower adjacent or attached to a mosque, from which the call to prayer is announced.

Minarets take many different forms—from the famous spiral minaret of Samarra, to the tall, pencil minarets of Ottoman Turkey. Not solely functional in nature, the minaret serves as a powerful visual reminder of the presence of Islam.

Qubba (dome)

Most mosques also feature one or more domes, called qubba in Arabic. While not a ritual requirement like the mihrab, a dome does possess significance within the mosque—as a symbolic representation of the vault of heaven. The interior decoration of a dome often emphasizes this symbolism, using intricate geometric, stellate, or vegetal motifs to create breathtaking patterns meant to awe and inspire. Some mosque types incorporate multiple domes into their architecture (as in the Ottoman Süleymaniye Mosque pictured at the top of the page), while others only feature one. In mosques with only a single dome, it is invariably found surmounting the qibla wall, the holiest section of the mosque. The Great Mosque of Kairouan in Tunisia has three domes: one atop the minaret, one above the entrance to the prayer hall, and one above the qibla wall.
