The Federal Territory Mosque which was opened in 2005 was modelled after the Sultan Ahmed Mosque in Turkey, with a blend of Middle Eastern and traditional local Malay designs. The rooftop of the main prayer hall is adorned with 22 domes with the main dome on top and several smaller domes surrounding it. These domes are made of epoxy resin and glass fibre fabric for lightness and durability.

Situated near the Government Office Complex along Jalan Duta, the construction of the Federal Territory Mosque began in 1996 and completed in 2000. It was officiated by the Yang di-Pertuan Agong Tuanku Syed Sirajudin on February 18, 2005. The design of the mosque is heavily influenced by the Blue Mosque in Istanbul,Turkey.

With its capacity to accommodate up to 17,000 worshippers, it is not just a mosque but also a community, education and research complex equipped with facilities and accommodation.
