The Old Summer Palace, known in Chinese as Yuanming Yuan (), originally called the Imperial Gardens (), and sometimes called the Winter Palace, was a complex of palaces and gardens in present-day Haidian District, Beijing, China. It is northwest of the walls of the former Imperial City section of Beijing. Widely perceived as the pinnacle work of Chinese imperial garden and palace design, the Old Summer Palace was known for its extensive collection of gardens, its building architecture and numerous art and historical treasures. Constructed throughout the 18th and early 19th centuries, the Old Summer Palace was the main imperial residence of Qianlong Emperor of the Qing dynasty and his successors, and where they handled state affairs; the Forbidden City was used for formal ceremonies. It was reputed as the "Garden of Gardens" () in its heyday.
