Kuala Kangsar (population 39,300) is the royal town of Perak, Malaysia, located at the downstream of Kangsar River, where it flows into the Perak River. It is the main town in the administrative district of Kuala Kangsar.
This place must have had a strange effect on Sultan Yusuf Sharifuddin Mudzaffar Shah of Perak who ruled from 1877 to 1887. Unlike many rulers who protected their royal palaces and strongholds by selecting their vantage points carefully where they could detect enemy approach from afar, the Sultan had his first royal palace built beside the riverbank. He then named it 'Istana Sri Sayong'.
