The Lincoln Log Cabin State Historic Site is an 86-acre (0.3 km2) history park located eight miles (13 km) south of Charleston, Illinois, U.S., near the town of Lerna. The centerpiece is a replica of the log cabin built and occupied by Thomas Lincoln, father of U.S. President Abraham Lincoln. Abraham Lincoln never lived here and only occasionally visited, but he provided financial help to the household and, after Thomas died in 1851, Abraham owned and maintained the farm for his stepmother, Sarah Bush Lincoln. The farmstead is operated by the Illinois Historic Preservation Agency.
