Yidongyuan (Chinese: 颐东苑社区; pinyin: Yídōngyuàn shèqū; lit. 'East Summer Palace Garden') is a government compound in Beijing, China which serves as the headquarters of the Ministry of State Security (MSS). The facility consists of an office complex and residential community occupying a full city block in the Xiyuan area of Beijing's Haidian District. Closed to the public, and separated by a perimeter wall, the secretive nondescript facility is believed to be staffed by approximately 10,000 intelligence officers and support staff.
Unlike foreign counterparts such as the American CIA's George Bush Center for Intelligence, the SIS Building housing the British MI6, or the Lubyanka Building of Soviet KGB and Russian FSB, Yidongyuan is distinct in housing employees and their families in apartments on site.
