Did observatories exist before telescopes? One example that still stands today is the Beijing Ancient Observatory in China.Starting in the 1400s astronomers erected large instrumentshere to enable them to measure star and planet positions withincreasing accuracy. Pre-telescopic observatories throughout the world date back to before recordedhistory, providing measurements that helped to determine when to plant crops, how to navigate ships, and when religious ceremoniesshould occur. It is interesting to compare the above picture to one taken in 1895.
