Masjid Zahir (Zahir Mosque) is situated in the heart of Alor Star city in Kedah and was built on 22 Rabiulawal 1330 (1912). The construction of the mosque was the brain-child of YTM Tunku Mahmud Ibni Almarhum Sultan Tajuddin Mukarram Shah. Its design draws inspirations from that of Masjid Azizi in Bandar Langkat, Northern Sumatera. The mosque has a build-up area of 39 x 39m with the main area of 19.50 x 19.50m surrounded by an eight-feet wide balcony comprising four verandas and five main domes as a symbol of the five Pillars in Islam. The mosque was officially declared open by the late Almarhum Sultan Abdul Hamid Halim Shah on Friday 6 Zulhijjah 1333 Hijri / 15 October 1915.
