The observatory, established in 1923, served as the prime meridian reference point for Italian maps until the 1960s instead of the Greenwich meridian.
The Astronomical Copernican Museum within the observatory contains 4000 volumes, including manuscripts and first editions from Copernicus and Ptolemy.
