The Cincinnati Observatory welcomes in the holiday season with a special open house event! We will be open for tours, safe solar viewing (weather permitting), holiday refreshments including a hot chocolate bar, and shopping in our out-of-this-world gift shop! We’ll also have a quartet singing all your holiday favorites, we’ll have take-home activities for kids, and guests will be invited to have a holiday picture taken by our special Galaxy Tree! We’re also hoping Santa will stop by for a visit as well. 

Admission is free, but we require reservations since space is limited as we continue observing Covid-19 protocols, which can be found here. Masks will be required inside the building

Register for the 1pm, 2pm or 3pm visit time here!
