Quincy IL | USA Illinois

Quincy serves as the county seat of Adams County and is the primary commercial and cultural hub for the "Tri-State Area" (Illinois, Missouri, and Iowa). It is situated on the bluffs overlooking the Mississippi River, approximately 180 km northwest of St. Louis.

Historical Timeline

Quincy was founded in 1822 and named after John Quincy Adams. Primary governance eras include its role as a key stop on the Mississippi River trade route, its status as the second-largest city in Illinois during the mid-19th century, and its 20th-century industrial development. The city's urban form was significantly defined by its 19th-century German immigrant population, which established extensive brick-paved streets and ornate residential architecture. A critical historical event was the 1838–1839 arrival of the Mormon pioneers, who were sheltered by Quincy residents after being expelled from Missouri.
