See through the oldest public telescope in the country.
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.
