Sultan Alaeddin Royal Mosque is also known as Masjid Alauddin or Masjid Bandar. The mosque was built in the early 1900s about 200 meters from Istana Bandar (Bandar Palace), the residence of the fifth Sultan of Selangor, Sultan Sir Alaeddin Sulaiman Shah, GCMG KCVO.
It is believed that the design of this yellow mosque originated from the Sultanate of Deli in Medan, Sumatera.
A fine example of classic Moorish and Mughal architecture, the mosque shares several similarities with another heritage landmark, the Sultan Abdul Samad Building in Kuala Lumpur, particularly in its domes and arches.
Sultan Alaeddin Royal Mosque’s interior is decorated with Qur’anic inscriptions and intricate wood carvings. Renowned journalist George L. Peet, who visited the mosque in its prime, revealed that its pulpit was often used by the Sultan himself to deliver sermons.
Within its vicinity are other attractions including Bukit Jugra (Jugra Hill), Makam Diraja Sultan Abdul Samad (Royal Mausoleum) and Muzium Insitu Jugra.
