The building was then converted to a museum after 4 years of renovation. It was finally opened by Sultan Ahmad Shah on 21 October 1976.
Pekan, located on the banks of the Pahang River 50 km south of Kuantan and 280 km from Kuala Lumpur, is the Royal Town of the Malaysian state of Pahang Darul Makmur.
The museum building was constructed in the 1920s during British Malaya. Since then, the building has been used for the official residence for British government, army barracks and official palace of Sultan Abu Bakar.
