Faisal Mosque.

Faisal Mosque is the mosque in Islamabad, Pakistan. Located on the foothills of Margalla Hills in Islamabad, the mosque features a contemporary design consisting of eight sides of concrete shell and is inspired by a Bedouin tent.The mosque is a major tourist attraction, and is referred as a contemporary and influential feature of Islamic architecture.

Construction

Construction of the mosque began in 1976 after a $120 million grant from Saudi King Faisal, whose name the mosque bears. The unconventional design by Turkish architect Vedat Dalokay was selected after an international competition.Without a typical dome, the mosque is shaped like a Bedouin tent, surrounded by four 260 feet (79 m) tall minarets. The design features eight-sided shell shaped sloping roofs forming a triangular worship hall which can hold 100,000 worshipers, while the surrounding porticoes and the courtyard up-to 200,000 more.

Hisotry

The impetus for the mosque began in 1966 when King Faisal bin Abdul-Aziz supported the initiative of the Pakistani Government to build a national mosque in Islamabad during an official visit to Pakistan.

In 1969, an international competition was held in which architects from 17 countries submitted 43 proposals. The winning design was that of Turkish architect Vedat Dalokay.[9] Construction of the mosque began in 1976 by National Construction of Pakistan, led by Azim Khan and was funded by the government of Saudi Arabia, at a cost of over 130 million Saudi riyals (approximately 120 million USD today). King Faisal bin Abdul Aziz was instrumental in the funding, and both the mosque and the road leading to it were named after him after his assassination in 1975. The mosque was completed in 1986, and used to house the International Islamic University. Many conservative Muslims criticized the design at first for its unconventional design and lack of a traditional dome structure, but most criticism ended when the completed mosque's scale, form, and setting against the Margalla Hills became evident.
