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, scouts and history buffs. We offer public astronomy programs and stargazing every Thursday & Friday evening and dozens of special events throughout the year.
When you explore the beautiful buildings and see through the large, historic telescopes, you'll step back in time and space.
