Pioneer Court is a plaza located near the junction of the Chicago River and Upper Michigan Avenue in Chicago's Magnificent Mile. It is believed to be the site of Jean Baptiste Point du Sable's original residence and trading post. In 1965, the plaza was built on the former site of his homestead as part of the construction of the Equitable Life Assurance Society of America building. The Jean Baptiste Point Du Sable Homesite was designated as a National Historic Landmark on May 11, 1976. John Kinzie, a prominent early settler, bought and expanded Point du Sable's post in 1800. The Plaza is bounded on the north by the Tribune Tower, on the east by 401 N. Michigan Avenue, on the south by the Chicago River, and on the west by Michigan Avenue, adjacent to the Michigan Avenue Bridge. In 2017, a newly designed Apple Inc. store was opened on the south side of the court, which created new levels linking down to the river.
