Antwerp is located in the former wetland region known until the 19th century as the Great Black Swamp. Antwerp was founded in 1841 on the Wabash and Erie canal and the center of town moved to its present location when the railroad was extended to that point. The village was named after Antwerp, in Belgium. In the late 19th century, Antwerp was the largest village in Paulding County; its economy was driven by lucrative local logging and tile mill industries. Accordingly, when the Wabash, St. Louis and Pacific Railway decided to erect a train station in the village, it was built larger than stations in most other communities in the region. After the train station closed in 1976, it was purchased by the local historical society; today, it is listed on the National Register of Historic Places as the Antwerp Norfolk and Western Depot.
