Istana Alam Shah, Royal palace in Klang, Malaysia

Istana Alam Shah is the official palace of the Sultan of Selangor in southern Klang. The present building replaced the earlier Istana Mahkota Puri and has 15 rooms built using wood and marble. It was extensively renovated in early 2000 under Sultan Salahuddin Shah.

An earlier palace, Istana Mahkota Puri, stood on this site from 1903, built during the reign of Sultan Sulaiman Shah and modelled on Kuala Lumpur's Sultan Abdul Samad Building. The Sultan lived there for 35 years until his death in 1938, and in the 1950s it briefly served as a student dormitory for nearby schools. It was demolished in October 1957 and soon replaced by the present palace.

Despite the Sultan having two other official residences, in Shah Alam and Putrajaya, most ceremonies of the Selangor royal family, including the coronation of a new Sultan, are held at Istana Alam Shah. The seventh Sultan of Selangor, Sultan Salahuddin Abdul Aziz Shah, was born here.

The palace grounds feature two horseshoe-shaped entrance porches, with one specifically reserved for royal family members and official dignitaries. The elevated terrain helps visitors orient themselves when exploring the outer areas of the property.

From its hilltop position, the residence overlooks Sultan Suleiman Shah Mosque, creating a visual connection between the royal and spiritual landmarks of the area. This elevated vantage point makes the setting feel distinct from the surrounding city.
