You stand beneath a 1949 water tower shaped like a giant Brooks catsup bottle, a restored roadside landmark beside Route 159.
Next to Route 159, just south of downtown Collinsville · Collinsville, IL
This 170-foot water tower was built in 1949 by the W.E. Caldwell Company for the G.S. Suppiger plant that bottled Brooks catsup. Volunteers saved it from demolition and restored it in 1995, and it joined the National Register of Historic Places in 2002 as a prime example of mid-20th-century novelty architecture. You see it beside Route 159 just south of downtown Collinsville, and each June the town holds a festival in its honor.
