The Wrigley Building: A Chewing-Gum Company Gives Michigan Avenue a Landmark
October 27, 2026
The Wrigley Building does not need to be Chicago's tallest tower to dominate a view. Its pale terra cotta, clock and illuminated crown stand at the bend where Michigan Avenue crosses the Chicago River. From the south, the turn in the street gives it an almost theatrical position. What looks like a particularly fortunate piece of skyline composition was also a calculated business decision: William Wrigley Jr. placed his company's headquarters at the entrance to a newly connected commercial district.
The building's history joins consumer advertising to city planning. A company selling small, inexpensive packages of chewing gum commissioned architecture intended to be recognized from far away. At the same time, public investment in a bridge and a wider avenue was changing the value and possibilities of the land around it. The Wrigley Building gave that change a visible symbol, while the new street system gave the company a stage it could not have created by itself.
Before the tower, the product
William Wrigley Jr.'s business did not begin with a grand building or even with gum. The city's landmark report describes his move from Philadelphia to Chicago in 1891 and his early sales of soap and baking powder. Premiums helped attract customers. Chewing gum offered with other merchandise became popular enough to become the main product. By 1893, Juicy Fruit and Spearmint were among the brands reaching a wider audience.
Wrigley's later success depended on distribution and advertising as much as on manufacturing. The landmark report traces nationwide campaigns using newspapers, streetcars and billboards, as well as the company's expansion through the 1910s. That background helps explain the headquarters. A building carrying the Wrigley name into the skyline was consistent with a business that understood repeated recognition as an asset. Architecture became a durable form of publicity.
It was also a statement about the company itself. A headquarters could bring offices together, but a conspicuous tower suggested stability and ambition beyond the daily sale of gum. The contrast between a five-cent consumer product and an elaborately made building became part of its appeal. The landmark report records contemporary phrases celebrating a structure "built by nickels." The monument made the cumulative scale of an ordinary purchase visible.
A bridge changes the map
Before Michigan Avenue became a continuous route across the river, traffic relied heavily on the crowded Rush Street Bridge. The land north of the river included warehouses, industry and smaller buildings, not the shopping corridor familiar today. Burnham and Bennett's 1909 Plan of Chicago supported widening Michigan Avenue and creating a more effective connection. Years of political, financial and property-acquisition difficulties separated the plan from construction.
The Michigan Avenue Bridge opened in May 1920. That project redirected movement and created prominent sites at the crossing. The Wrigley lot was especially visible because of the river bend and the angle between the avenue's northern and southern segments. A building placed there could be seen along an extended approach. Its identity would not depend only on someone standing immediately in front of the entrance.
The distinction between public infrastructure and private development is important. The Wrigley Building is often praised as if a single owner transformed the entire district. The bridge and street improvements made its location possible and encouraged other investment. Wrigley responded early and decisively, commissioning a building that helped give the new route an architectural character. The commercial corridor emerged through the interaction of those public and private choices.
Designing for an awkward and valuable site
Graham, Anderson, Probst & White designed the headquarters, with Charles G. Beersman leading the design work according to the building's own history and the city report. The south structure opened in 1921. Its plan responded to an irregular lot rather than imposing a simple rectangular slab. Above the principal office mass, a tall clock tower turned the site's visibility into a recognizable silhouette.
The structure was modern steel construction, with concrete protection and foundations extending to bedrock. The exterior language was historical. That pairing was common in the period, but the Wrigley Building made especially effective use of it. The steel frame enabled a commercially useful tall building; the surface and tower associated the business with older ideas of civic grandeur. Practical office space and a carefully composed public image were designed together.
The south tower rose to about 398 feet, just below the city's 400-foot limit then in effect, according to the landmark report. Its height was therefore shaped by regulation as well as ambition. The upper composition made full visual use of that allowance. The architecture did not simply pile up identical occupied floors until it reached a limit; it treated the upper portion as the building's principal identifying feature.
What style is it?
Different institutional accounts use different labels. The Chicago Architecture Center calls it Spanish Colonial Revival, while the city's landmark report describes Beaux-Arts organization and French Renaissance detail. The building's own account discusses its relationship to the 1893 World's Columbian Exposition and the Giralda tower in Seville. These descriptions need not be forced into a single exclusive category. They identify different parts of a deliberately mixed design.
The overall composition has the formal hierarchy of a monumental commercial building: a defined base, repeated office stories and an emphatic top. The tower draws on a Spanish precedent, while much of the ornament borrows French Renaissance forms. The white surfaces and nighttime illumination recall the visual world of the fair's White City. The building makes sense as a synthesis of those references rather than a perfectly pure example of one style.
That mixture also helps explain why the clock tower is so memorable. It offers a distinct outline even when the decorative details cannot be seen. At a closer distance, urns, animals, foliage and other molded forms give the surface a different scale of interest. Historical references work both as large shapes and as small components. A person crossing the bridge and a person standing at the entrance receive different versions of the same design.
White is not just one color
More than 250,000 terra-cotta pieces originally clad the building, made by the Northwestern Terra Cotta Company. Six subtly different shades were used, lightening the effect as the building rises. The exact appearance changes with sun, shadow and weather, but the graded treatment was intentional. The facade was designed to appear lighter and more distant toward the top, making the tower seem less like a heavy extension of the block below.
Terra cotta was particularly useful for this kind of architecture. It could produce repeated units as well as modeled ornament, allowing a large facade to combine regularity and detail. Yet a white glazed surface needs maintenance to keep the intended effect. The city's report notes that many pieces have been replaced during the building's life. The familiar appearance is therefore the product of continuing repair, not proof that every visible tile is original.
Night lighting was part of the concept from the beginning. Reflector systems made the pale building stand out after dark. The Chicago Architecture Center and landmark report describe interruptions during World War II, lighting replacement and the energy crisis of the 1970s. Those exceptions are worth remembering: illumination is an operating choice with costs and circumstances, even when a century of photographs makes it seem an unchanging architectural fact.
One building becomes a pair
The initial success led Wrigley to commission a north annex, completed in 1924. That explains why descriptions sometimes give the Wrigley Building a 1924 completion date although the south tower opened three years earlier. The name covers a connected complex, not a single construction event. Its two principal sections work together along Michigan Avenue, with the taller south clock tower providing the dominant accent.
Bridges between the structures are part of their identity. They allow the two buildings to operate as a linked property while leaving open space between them. The pedestrian plaza also developed over time; the Chicago Architecture Center dates its creation to 1957. The familiar experience of looking through the gap or standing between the two buildings is therefore another later layer, not simply the unchanged arrangement of opening day.
Looking up from that space changes the building again. From the avenue or across the river, the complex reads as a unified white landmark. Between its parts, the bridges and walls reveal a working office property with connections, recesses and different levels. That close view is a useful correction to the postcard image. The Wrigley Building was designed to be seen, but also to organize the movement and work of its occupants.
A name that outlasted the original offices
The company no longer maintains offices here, according to the Chicago Architecture Center, but the name remains. The building's official history identifies Joe Mansueto as owner since 2018, and the current management site continues to market it as an office property. Chicago landmark designation came in 2012. These later chapters separate ownership, occupancy and identity, which are often casually treated as the same thing.
The Wrigley Building's achievement is not simply that a gum manufacturer paid for an ornate headquarters. It is that the architecture joined a company name to a major piece of the city's public geography. The bridge, river bend, white surfaces, clock and night lighting reinforce one another. Even as tenants change, that relationship continues to make the building a point of orientation: a commercial address that became part of how Chicago recognizes itself.
Visiting
The property is at 400-410 North Michigan Avenue. It remains a working office complex, not a public observation tower. The exterior, bridges and publicly accessible plaza are the main independent architectural experience; the historic clock tower is not advertised as a general-access viewing deck. Current use and address were checked on the official management and Chicago Architecture Center pages on October 27, 2026. Check any special-tour access separately.
Where can you eat or drink at the Wrigley Building?
Ghirardelli operates an Ice Cream & Chocolate Shop at 400 North Michigan Avenue. It is an on-site stop for sundaes, chocolate and drinks, not an upper-floor restaurant with a tower view. Its official store page lists Sunday-Thursday, 10 a.m.-10 p.m., and Friday-Saturday, 10 a.m.-11 p.m. Hours were read on October 27, 2026. Confirm before visiting, especially on holidays.
