|Built in 1836 for Henry B. Clarke, the Clarke House Museum is Chicago's oldest house. It is operated as a house museum by the Planning Division of the Chicago Department of Cultural Affairs. This Greek Revival style house shows what life was like for a middle-class family in Chicago during the city’s formative years before the Civil War. It has survived fires and two moves, and is now located in the Prairie Avenue Historic District. Guided tours of the house are available. Clarke House presents an outdoor film festival during the summer, as well as other seasonal events and occasional exhibitions.
