Purple Mountain Observatory
The Purple Mountain Observatory (PMO) evolved from the former Institute of Astronomy, which was established in 1928 as one of the first eight institutes of the Academia Sinica. In 1934, the institute completed the construction of the observatory at Purple Mountain in Nanjing and the Institute of Astronomy changed its name to PMO in 1950.
