Tuanku Mizan Zainal Abidin Mosque, Modern Islamic mosque in Putrajaya, Malaysia.

Tuanku Mizan Zainal Abidin Mosque, called the Iron Mosque, stands in Precinct 3 opposite the Palace of Justice. About 6,000 tonnes of steel make up roughly 70% of the structure, the rest concrete. Its broad flat roof carries a ribbed pale dome, and the facade is clad in architectural wire mesh from Germany and China set in pointed arches. The roof edges, 40 feet long, shelter worshippers praying outside the main hall.

Construction of the building took place between 2004 and 2009 and it was named after Malaysia's 13th Yang di-Pertuan Agong. This period marked an important phase of modern religious architecture in the country.

The mosque is nicknamed Masjid Besi, the Iron Mosque, after the roughly 6,000 tonnes of steel that make up about 70% of its structure. Its interior carries the Al-Asmaul-Husna, the 99 names of God, in Thuluth calligraphy, and the main prayer hall entrance bears verse 80 of Sura Al-Isra. Worshippers reach it from Dataran Putrajaya across the Kiblat Walk, a 13,639 m² skyway landscaped with water pools modelled on the Alhambra.

The mosque stands in Precinct 3, opposite the Palace of Justice and beside the Islamic Complex Putrajaya. From Dataran Putrajaya, reach it on foot across the Kiblat Walk skyway, a 13,639 m² landscaped route with water pools. Parking is in the basement. The 40-foot roof edges shelter those praying outside the main hall from rain.

The mosque has no permanent ceiling fans or air-conditioning units; it is cooled by a district cooling gas system instead. About 6,000 tonnes of steel make up roughly 70% of the structure, the rest being concrete, which is why it is called the Iron Mosque.
