World's Largest Catsup Bottle Festival in Collinsville
The World's Largest Catsup Bottle Festival is an annual birthday-party-style celebration held in Collinsville, Illinois, honoring the Brooks Catsup Bottle water tower, a 170-foot novelty water tower shaped like a ketchup bottle. Long held in July and shifted in recent years toward June, the festival features a car show, vendors, and live entertainment at Herald Square.
Its Americana oddity and local identity make it a good weird-event row.
