  • Aledo received the Illinois Premier Main Street Designation in 2007 and 2008.

Chartered in 1835, Mercer County in Illinois was part of the Old Northwest Territory and the Military Tract. Abraham Lincoln, as part of the militia in the Blackhawk War, marched through the county in 1832 and returned in 1834 to survey the town of New Boston.

Or, take a stroll through historic neighborhoods and view grand homes built in the late 1800s.

New Boston features Lock and Dam 17, the Boston Bay Conservation Club, the New Boston Museum, and Surgeon Bay Park. Much of the natural area surrounding New Boston is part of the Port Louisa National Wildlife Refuge. The river valley at New Boston is surrounded on both sides by gently rolling bluffs interspersed with rich parcels of wetlands that provide critical wildlife habitat; especially critical habitat for migratory birds. As a young lawyer, Abraham Lincoln surveyed the town in 1833.

Keithsburg claims Illinois's largest state forest, Big River, Mark Twain National Wildlife Refuge, Riverside Campground, Sharon L. Reason-Keithsburg Museum, and a great fish fry in June.

The western portion of the county along the Mississippi River is part of the Yellowbanks Territory. Named Yellowbanks by the Sauk and Fox Indians because of the yellow, sandy soil along the riverbank, New Boston and Keithsburg are the focal points of yellowbanks in Mercer County. Annual events in the county include: the Edwards River Antique Tractor Show in New Windsor, the Firemen's Fish Fry in Sherrard, and the New Windsor Fair and Rodeo in August.
