What Is Marina City in Chicago?

Marina City is a mixed-use architectural complex in downtown Chicago, located alongside the Chicago River. Designed by architect Bertrand Goldberg, the development was envisioned as a community where people could live, work, and enjoy entertainment without traveling far from home.

Its two residential towers rise approximately 65 stories, making them prominent features of the downtown skyline. Their circular forms and repeating balconies stand apart from the rectangular glass skyscrapers surrounding them.

The original development included apartments, parking facilities, offices, restaurants, a theater, and recreational amenities. This combination made Marina City an ambitious experiment in urban living during the 1960s.

Today, the towers remain among Chicago's architectural landmarks, attracting photographers, history enthusiasts, and visitors interested in the stories behind the city's most recognizable buildings.

The History of Chicago’s Corncob Towers

The history of Marina City began in 1959, when Chicago faced a challenge familiar to many American cities. Middle-class residents were increasingly moving to the suburbs, leaving downtown areas more focused on offices and businesses than residential life.

Architect Bertrand Goldberg believed cities needed to give people a compelling reason to stay. His solution was to create a development that combined housing, recreation, shopping, and workplaces in one location.

Construction of the residential towers took place during the early 1960s. The first tower was completed in 1962, followed by the second in 1963. The broader complex continued developing, with its theater completed in 1967.

The project challenged conventional ideas about skyscrapers and how urban communities could function. Rather than creating two ordinary residential buildings, Goldberg imagined a lively environment where residents could enjoy the convenience of downtown living while remaining connected to the city around them.

This vision helped make Marina City an important chapter in Chicago's architectural history and an early example of the mixed-use developments that are common in modern cities.

Why Are They Called the Corncob Towers?

The nickname comes from the buildings' distinctive appearance. Each tower features rows of curved balconies that wrap around its central structure, creating a pattern that resembles the kernels of an ear of corn.

From across the Chicago River, the resemblance becomes particularly striking. The repeating balconies give the buildings a sculptural quality that makes them easy to recognize, even among Chicago's many impressive skyscrapers.

The design also serves a practical purpose. The curved balconies provide outdoor space for residents and offer views of the river, surrounding buildings, and downtown streets.

At a time when many modern buildings favored straight lines and simple geometric forms, Marina City's rounded design offered something different. Its bold appearance helped establish the Corncob Towers as an enduring symbol of architectural creativity.

Bertrand Goldberg: The Architect Behind Marina City

To understand Marina City, it helps to know more about the architect who imagined it.

Bertrand Goldberg was born in Chicago in 1913 and developed an architectural approach that combined modernist ideas with a strong interest in how people use buildings.

Rather than designing structures purely as visual statements, Goldberg wanted architecture to improve everyday life. He believed buildings should respond to people's needs and create opportunities for communities to thrive.

Marina City reflected this philosophy. The project brought residential spaces, parking, offices, and entertainment facilities together in a single development.

Its unconventional design also demonstrated Goldberg's willingness to experiment with form and materials. The result was a pair of towers that looked dramatically different from the surrounding skyline while serving a practical urban purpose.

What Makes Marina City’s Architecture Unique?

Marina City's architecture stands out because of its combination of sculptural design and engineering innovation.

The towers were constructed primarily from reinforced concrete, allowing Goldberg to create their distinctive rounded forms. Their central cores support the structures, while the curved floor plans and projecting balconies establish the buildings' recognizable appearance.

When completed, the residential towers were recognized as the world's tallest reinforced-concrete buildings, marking an important moment in high-rise construction.

Their design also reflects the ambition behind the wider complex. Parking occupied the lower floors of the towers, while apartments filled the upper levels. This arrangement helped integrate practical city infrastructure into the residential development.

More than six decades later, Marina City continues to demonstrate how creative architecture can challenge expectations while responding to the needs of urban residents.

Visitors interested in exploring these design features alongside other notable skyscrapers can consider the 90-minute Chicago River Architecture Tour, which explores all three branches of the Chicago River and showcases a broad collection of architectural landmarks.

Marina City and Chicago’s Changing Skyline

Over the years, Marina City has witnessed Chicago's skyline evolve around it. New office towers, glass skyscrapers, and contemporary developments have transformed the surrounding downtown landscape.

Yet the Corncob Towers remain distinctive. Their exposed concrete, rounded balconies, and symmetrical arrangement create a striking contrast with the reflective glass buildings nearby.

The complex has also appeared in films, television, photographs, and other forms of popular culture, helping introduce its unusual design to audiences around the world.

Its importance extends beyond its appearance. Marina City helped popularize the idea that residential buildings could form part of a larger mixed-use environment, bringing homes and everyday amenities closer together.

For architecture lovers, it represents an important chapter in Chicago's ongoing story of experimentation, reinvention, and urban growth.
