The Old National Palace (Malay: Istana Negara), originally the palace of Malaysia's highest head of state, is situated in Bukit Petaling on Jalan Syed Putra, covering an area of 28 acres (110,000 m &), overlooking the corner of the Sungai Klang River. On November 15, 2011, it was relocated to the new National Palace and its original site was changed to a memorial museum. Originally built in 1928 by Chen Zhenyong, a wealthy Chinese businessman, the National Palace was converted into a banquet hall for Japanese officers when Japan occupied Malaya. After the surrender of Japan, the government of Selangor State bought the building as the palace of the Sultan of Selangor and sold it to the palace of the Federal Government as the supreme head of state until 1957. Since then, the palace has been revised and expanded several times, the largest of which was in 1980, because the ceremony of the supreme head of state ascended the throne was moved from the Aduraman Hall of Donggu (today's tourism bureau) to the National Palace. In 2011, the new National Palace was built on Ambassador Road in Kuala Lumpur. The New National Palace is larger than the old one. The inauguration ceremony of the 14th supreme head of Malaysia, Sultan Duangu Aduharin, was held at the New National Palace, which also replaced the old National Palace as the official residence of the supreme head of Malaysia. The old National Palace became a Royal Museum for people to visit.
