That history includes buildings no longer standing but still tells the stories of the people who lived or worked there and their times.

The newly updated St. Charles County Historical Society website is a night-and-day improvement from its previous version. The layout is clean, intuitive, and visually appealing, making it far easier to navigate and find the information you need. Historical resources that were once buried in clutter are now organized into clear categories, and the improved search function allows you to quickly locate documents, photos, and archives.
The updated design also showcases St. Charles County’s rich history in a more engaging way, with high-quality images, interactive features, and well-written descriptions. Whether you’re a casual visitor or a dedicated researcher, the site now feels like a welcoming, accessible hub rather than an outdated archive.
The mobile responsiveness is another major plus—pages load quickly and display beautifully on any device, which was a challenge in the past. Overall, the new site not only honors the past but also brings it into the present, making local history more approachable than ever before.
Kudos to the team for bringing this valuable resource into the modern era while preserving its historical

"Hello, Amy:
I would like to sincerely thank you and Joan Koechig for allowing me to go
through Andrew McColloch’s files regarding the St. Charles County Airport. This
information is exactly what I have been looking for in trying to better
establish a timeline of how the St. Charles County Airport came to be. The
amount of information is incredible and, even though I haven’t had a chance to
go through all of it yet, what I have seen is fascinating and will definitely
help me to track the development of the airport.
I am so glad that this information came to light and did not sit on a shelf unnoticed. Again, many, many thanks and best wishes to you and Joan."

As a former museum docent and longtime history buff, it was fantastic to see the great work the St. Charles Historical Society has been doing and to learn more about the local history of St. Charles, as well as how it relates to the state and the country
Highly recommend for anybody who is interested in history, even casually. Hope to be able to visit again sometime in the not too distant future!
Thanks and have a great rest of your weekend.
