A question that has repeatedly come up here at the Archives is 'where was the College located when it was in Plainfield?' (For those who don't already know, the College was organized in 1861 as Plainfield College. We moved to Naperville in 1870 as North-Western College). The Sharon Evangelical Church was instrumental in the choice of location by donating land and building/money for the College and thanks to their timeline on the website, we gathered enough information to track it down more specifically.
With the online Sanborn map from 1893 in hand, my student assistants Adam and Brittany and I all headed to Plainfield this past Friday for a research trip - to investigate what is there currently and take some photos. Turns out the Plainfield Academy on Lockport at Dillman is currently on the land originally used by the College.
Special thanks to a member of the congregation who let us into the Sharon United Methodist Church where we found an excellent photo on display showing exactly where the replacement building (the original College building was destroyed by fire in the early 1870s and rebuilt by Plainfield citizens as a public school) was located. The church is in the center of the photo and the old school building is in the upper right corner.
