Founded in 1837 Collinsville had moved from an agrarian and small business community to a bustling industrial town by the turn of the 20th century. The Great Depression and industrial competition altered this course. However, the always strategic location with proximity to rivers, rail, and multiple highways encouraged growth towards a residential and suburban service-oriented town. One of the exciting recent developments is the popular and growing hospitality district. For over 175 years Collinsville has grown and changed, adapting to new developments and ideas. This book provides a visual history, primarily through picture postcards, of the changing community.
