In the 18th century, Anders Celsius
Anders Celsius was a Swedish astronomer. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germany, Italy and France. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 he proposed the Celsius...

to buy a large stone house of medieval origin in central Uppsala, where he had an observatory constructed on the rooftop. Celsius both worked and had his personal living quarters in the house. This observatory remained in use until the new observatory, now known as the "old observatory", was built in 1853. The Celsius house itself still remains as one of few older buildings on a modern shopping street, but the observatory on the roof was demolished in 1857.

, also conducted research on solar radiation at the observatory.
In 2000 the observatory merged with the Institute of Space Physics to form the Department of Astronomy and Space Physics and moved to the Ångström Laboratory. In 2008, another merger resulted in the Department of Physics and Astronomy, Astronomy and Space Physics becoming one of its divisions.
In addition to facilities in Uppsala, the observatory maintains the Kvistaberg Observatory
