LARAMIE, Wyo. – January 16, 2025 – Wyoming State Parks announces the partial closure of the Historic Prison Building at the Wyoming Territorial Prison State Historic Site for the installation of a replacement lighting system and improvements to the second-floor galleries.

"The lighting system in the Prison Building failed multiple times during the 2024 summer season, so we are excited that this work is underway. This project has allowed us to fix a recurring problem with the lighting system and improve the gallery lighting on the second floor," said Jessica Lira, superintendent for the Wyoming Territorial Prison State Historic Site. 

As of January 16, the first floor of the Prison Building will be open on Saturdays from 10 a.m. -3 p.m. This includes the cell blocks and the Butch Cassidy exhibit. The second floor is the most impacted area and will be closed until the project is complete. Additional closures may be needed during the installation to ensure work can be safely completed. For the latest information, please refer to the Wyoming Territorial Prison State Historic Site's social media pages. 

The Broom Factory, Warden's House, and Science on the Range exhibit in the Horse Barn Building will be open during regular winter hours, Thursday through Saturday, from 10 a.m. to 3 p.m.
