The Martin–Boismenue House, built about 1790 by North American frontiersman Pierre Martin, is one of the oldest surviving structures in Illinois.
The Martin–Boismenue House is a single-family house and historic site in East Carondelet, Illinois about 1.5 miles East of the Mississippi River. The house, built circa 1790, is owned by the Illinois Historic Preservation Agency. Although the house was built after the American Bottom had been ceded to the young United States of America, the house reflects the French Colonial architectural traditions of the Mississippi River valley. The region immediately around Cahokia, Illinois continued to speak French for several decades after the cession.
