We loved hosting the students from Allegan Online & Adult Education for a recent field trip at the Old Jail Museum! 🗝️

Exploring local history is always more meaningful when it’s shared, and we’re grateful for the opportunity to welcome groups like theirs through our doors.

If you’re part of a school, club, or community group interested in scheduling a visit outside of regular museum hours, we’d love to hear from you. Contact the museum to plan your tour!

On Friday, our K-8 students took a field trip to the Allegan County Historical Society Old Jail Museum. Thank you for hosting us - the students learned a lot and had a great time!
