Equitable Building, Commercial skyscraper on Michigan Avenue, Chicago, United States
The Equitable Building at 401 North Michigan Avenue is a commercial office tower in Chicago, Illinois, built on the north bank of the Chicago River at its junction with Michigan Avenue. The exterior is clad in aluminum curtain walls arranged around a central structural core, giving the building a clean, grid-like face.
The site was home to Chicago's first permanent Euro-American settlement in the late 1700s, long before the city took shape around it. The tower itself was built in the mid-20th century, when Michigan Avenue was developing into one of Chicago's main commercial corridors.
At the base of the building, Pioneer Court is an open plaza with a fountain and a bust honoring Jean Baptiste Point du Sable, widely regarded as Chicago's first permanent settler. The plaza is used as a gathering spot and offers a moment of pause along one of the city's busiest stretches.
The building sits next to the Michigan Avenue Bridge, making it a natural starting point for walks along the riverfront or up Michigan Avenue. Visitors arriving on foot will find the area easy to navigate, with open sightlines toward the bridge and the river on one side.
During construction, old railway cars were sunk into the ground and used as caissons to support the foundations in the wet soil near the river. This approach is invisible from street level but reflects how builders adapted to the challenging ground conditions along the Chicago riverbank.
