James Robert Williams House

The James Robert Williams House is a historic house located at 310 E. Main St. in Carmi, Illinois. The house was built in 1896 for James Robert Williams, a U.S. Representative and political ally of William Jennings Bryan. Prominent residential architect George Franklin Barber designed the red brick house in a blend of the Romanesque Revival and Queen Anne styles. The house has three corner towers, two with crenellated tops and one with a double bell roof; the towers cause the building to resemble a castle. The house's front entrance is surrounded by an arched porch with a balcony on its roof. A loggia is located above the entrance on the house's third level.

The house was added to the National Register of Historic Places on January 29, 1987.
