Horseradish Capital of the World

About this city

Also known as: Horseradish Capital of the World

Collinsville is a historically and archaeologically significant city located primarily in Madison County, just a few miles east of St. Louis, Missouri. Settled in the early 19th century by entrepreneurial brothers from Connecticut, the city developed a diverse economy rooted in coal mining, brick manufacturing, and agriculture, earning fame as the Horseradish Capital of the World. It is most profoundly notable for encompassing the Cahokia Mounds, a pre-Columbian Native American city that represents one of the most vital archaeological sites in North America.
