About Old State Capitol State Historic Site

The Old State Capitol State Historic Site in Springfield, Illinois is a Greek Revival statehouse completed around 1840 that served as Illinois’ capitol through the 19th century. It is a focal point of Illinois political history and 19th century civic architecture.

Restored public rooms include the House and Senate chambers and a central rotunda, presented with period furnishings and legislative-era details that illustrate how the building functioned as a working capitol. Interpreters and exhibit panels focus on mid-19th century state government and notable events connected to the building.

Construction took place in the late 1830s and the building served as the Illinois state capitol through the mid 1870s. It is closely tied to Abraham Lincoln and other Illinois political figures; the site has been preserved and restored to reflect its 19th century appearance.
