The Observatory and its Instruments

Part of the Sources and Studies in the History of Mathematics and Physical Sciences book series (SHMP)

Construction of the Astrological Commission’s headquarters and observatory began in 1279. The compound measured roughly 123m × 92m, with a main building 17m tall. It occupied, more or less, the site of today’s Chinese Academy of Social Sciences on the north side of Jianguomennei Avenue (Jianguomennei dajie 建国门内大街), within a long walk of the Forbidden Palace. The southeast corner of its walled compound fell close to the present-day Jianguomen subway entrance. Not a trace of the observatory remains.
