The Jarrot Mansion State Historic Site is located in the historic town of Cahokia, Illinois.  Cahokia is the oldest town on the Mississippi River, originally founded in 1699 by French Canadian priests as a mission to the Cahokia and Tamaroa Indians.   The village evolved into an agricultural and commercial center during 18th century.
