We are a fully functioning 19th century observatory used daily by the public and amateur astronomers, civic organizations, teachers and students, and history buffs.
Step back in time and space.
Explore the beautiful buildings and see through the large, historic telescopes which saw first light in 1845 and 1904.
Providing the astronomical pictures of our generation, the Hubble Space Telescope turns 25.
Two of Cincinnati's fabled seven hills are named because of us. The science of meteorology started here. And our main building, built in 1873, was designed by Cincinnati's premier architect.
