Imperial Ancestral Temple

The Imperial Ancestral Temple, or Taimiao (simplified Chinese: 太庙; traditional Chinese: 太廟; pinyin: Tàimiào) of Beijing, is a historic site in the Imperial City, just outside the Forbidden City, where during both the Ming and Qing dynasties, sacrificial ceremonies were held on the most important festival occasions in honor of the imperial family's ancestors. The temple, which resembles the Forbidden City's ground plan, is a cluster of buildings in three large courtyards separated by walls.
