Alâeddin Jugra Mosque, Royal mosque in Jugra, Malaysia

Alaeddin Mosque stands in Kampung Bandar, Jugra, near the Langat River. Built between 1903 and 1905, its design draws on architecture from the Deli Sultanate in North Sumatra. The mosque was gazetted as a National Heritage Site in 2008.

Construction ran from 1903 to 1905, and Sultan Alaeddin Suleiman Shah ibni Raja Muda Musa opened the mosque in 1906, the same period as Istana Bandar. It was gazetted as a National Heritage Site in 2008 under the National Heritage Act 2005, after earlier listing as an old monument and historical site on 24 July 1980.

The mosque is also called Masjid Bandar, after Kampung Bandar, the village beside the Sungai Langat where it stands. Sultan Alaeddin Suleiman Shah used it for Friday prayers and for gatherings with local residents and guests. It was gazetted as a National Heritage Site in 2008.

The mosque stands in Kampung Bandar, Jugra, near the Langat River and Kampung Pasir Jugra, south of Klang in Kuala Langat District. It is an active place of worship, so dress modestly and time a visit outside Friday prayers.

The building was designed by a regional Sultan drawing inspiration from a kingdom in North Sumatra's sultanate. This connection shows an exchange between Malaysian and Indonesian design traditions of that era.
