Located at the corner of Front and Main Streets in Petersburg, the Donald Barger House is a well preserved example of the hall parlor cottages located in Petersburg and throughout Boone County, built ca. 1880. The interior of the house contains unusually decorative woodwork, including: black iron mantles with gold stenciling, a built-in cupboard and unusual trim work. A porch was added to the kitchen entrance in the early 20th century.
