What stands out about Vandalia’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
On August 17, 1838, Benjamin Wilhelm, a settler from Pennsylvania, settled near what is now the intersection of U.S. Route 40 and US Route 25-A. He built his home and a small general store as a stop and resting place for travelers heading west. The small town began to attract travelers and businessmen, and on February 7, 1848, the town was incorporated as "The Village of Vandalia" with Benjamin Wilhelm as its first mayor. The village was laid out in 38 lots including a church, hotels, blacksmiths shops, a steam sawmill, meat markets, and a carriage shop. It was named after Vandalia, Illinois.
