city, seat (1821) of Fayette county, south-central Illinois, U.S. Vandalia lies on the Kaskaskia River, about 70 miles (115 km) southeast of Springfield. Its name is of unknown origin but is thought to be derived from either a Vandal tribe, a Dutch settler family, or a small Native American tribe. The city was laid out in 1819 and served as the state capital until government functions were transferred to Springfield in 1839. The Vandalia Statehouse (1836), the third built in the city, is preserved as a state historic site; across from the statehouse building is a life-size statue of Abraham Lincoln. Lincoln and Stephen A. Douglas served in the legislature there, and in the Supreme Court room Lincoln received his license to practice law. Vandalia is the site of one of the 12 Madonna of the Trail statues (dedicated 1928) built by the Daughters of the American Revolution; the statue, on the statehouse grounds, marks the western terminus of the Cumberland (National) Road. Vandalia's economy is based on agriculture (corn [maize], soybeans, wheat, and livestock) and manufacturing (plastics and mechanical seals). A state correctional centre is just north of the city. Ramsey Lake State Park (north) and Carlyle Lake Wildlife Management Area (southwest) are nearby. Inc. 1821. Pop. (1990) 6,114; (2000) 6,975.
