Collinsville has two very popular Route 66 attractions - Cahokia Mounds, a World Heritage Site and archeologically important Native American civilization; and the 1907 Brooks Catsup Bottle Water Tower, a fun and tangy landmark advertising Brooks Tomato Products Company condiments.

Take a drive for some photos in front of the World’s Largest Catsup Bottle and climb to the top of the biggest earth mound in North America with an educational visit to the Cahokia Mounds interpretive center to see recovered artifacts and get to know the history of the ancient Cahokian people.

Collinsville is also home to many standing service stations from Route 66’s heyday including the 1970s Lowell’s Mobil Station, a 1950s gas station (now LaDrew Automotive), and a 1920s cottage-style gas station called Eck Auto.
