Events in Collinsville

Some of the most authentic and eclectic events in the Great Rivers & Routes region are held in Collinsville.

Thousands of people pack the streets of Uptown Collinsville to celebrate their Italian heritage – at least they're Italian on that day – for the Italian Fest every September. In the summer, it's all horseradish all the time at the Horseradish Festival, a celebration of the city's status as the Horseradish Capital of the World. The events start there, but they don't end there. Take a look at more here.
