Masjid ini dihiasi dengan lima kubah utama sebagai simbol lima Rukun Islam.

This mosque was built in 1912, a contributory effort of YTM Tunku Mahmud Ibni Almarhum Sultan Tajuddin Mukarram Shah. The site of this mosque before it was built was the cemetery of the Kedah warriors who had died while defending Kedah from Siam (1821). The architecture of the mosque was inspired by the AZIZI Mosque in Langkat town, north Sumatera. This mosque is enhanced with five prime large domes symbolizing the five Islamic principles.

Its official launching ceremony was held on Friday, 15 October 1915 by the late HRH Sultan Abdul Hamid Shah. Tunku Mahmud read the Friday sermon while HRH Sultan Abdul Hamid Shah led the Friday prayer. At the back of the Zahir Mosque, is the Syariah Court building complex and the Centre for Basic Education for Children.
