From the explanation

“You can take a subway ride to visit this observatory in Beijing, China but you won’t find any telescopes there. Starting in the 1400s astronomers erected devices at the Beijing Ancient Observatory site to enable them to accurately measure and track the positions of naked-eye stars and planets .”
