The Commission House, variously called the West Garden Hall and the Office of the Provisional President, was built in 1909 by Duanfang, the 80th Viceroy of Liangjiang, who visited Europe just before the construction started. The construction finished in 1910, during the period of Zhang Renjun, the last Viceroy of Liangjiang. From 1 January 1912, the house was used as the office of the provisional president by Sun Yat-sen, thus becoming one of the birthplace of the Republic of China. The first cabinet council of the provisional government was held in the house as well. Since 1927, the house was served as the seat of the Military Affairs Commission, which grasped the real power of the Nationalist Government. Today this yellow house is also a popular tourist attraction in the Presidential Palace.
