World's largest Catsup Bottle
Collinsville is a city in Southern Illinois in the Saint Louis Metro East area. The "Horseradish Capital of the World," 85 percent of the world's horseradish is grown in Collinsville and the surrounding area.
Collinsville is a small city and is a suburb of St. Louis in the Metro East. It is roughly in the middle of a string of towns extending from Edwardsville to Belleville. The city consists mainly of the original town on the river bluff and an expansion built up around I-70 at the base of the river bluffs. This part has all/most of the major restaurant chains, hotels, and several "big box" stores. You will also find the Gateway Conference Center  in this area.
Up on the bluff you will find the older part of the city. It is largely a white, blue-collar midwestern town. It has more of a small-town feel than a suburban feel. The original downtown is called "uptown"  to differentiate it from the newer commercial area by I-70. Although it was run-down for the past few decades, "uptown" is currently seeing a revitalization.
Collinsville is located at longitude 90W, making it one quarter of the way around the world from Greenwich.
The Mississippi River makes this area humid, though temperatures are generally moderate. Storms can occur at any time of the year.
