Tallest Buildings in Des Moines: Downtown Skyline Rankings

In the sweeping landscape of the American Midwest, where the horizon is often defined by the rhythmic rise and fall of rolling hills and cornfields, the Des Moines skyline stands as a bold architectural punctuation mark. For a city of its size, Des Moines, Iowa, possesses a surprisingly dramatic vertical profile—a narrative of urban ambition that has evolved from the ornate masonry of the early 20th century to the gleaming glass of the modern era.

To understand the Des Moines skyline is to understand the history of Iowa’s insurance and financial sectors. As these industries flourished, the city reached higher, creating a “clamber for the clouds” that has resulted in a compact but impressive downtown core. Here is the definitive ranking and narrative of the tallest buildings currently defining the Des Moines horizon.

1. The Undisputed Monarch: 801 Grand (630 Feet)

Since its completion in 1991, 801 Grand (also known as the Principal Building) has stood as the undisputed king of the Iowa sky. At 44 stories and 630 feet, it is not only the tallest building in Des Moines but the tallest in the entire state of Iowa.

The narrative of 801 Grand is one of postmodern prestige. Designed by the renowned architectural firm Hellmuth, Obata & Kassabaum (HOK), the building is clad in absolute granite and energy-efficient glass. Its most striking feature is the eight-sided copper pyramid that crowns the structure.

• The Icon Factor: On a clear day, the shimmering copper top can be seen from miles away, serving as a lighthouse for travelers approaching the city on I-80. It houses the headquarters of Principal Financial Group and represents the city’s status as a global insurance hub.

2. The Modernist Giant: Ruan Center (460 Feet)

Standing at 36 stories, the Ruan Center held the title of the city’s tallest from 1975 until the arrival of 801 Grand. This building represents a different chapter in the Des Moines story—one defined by the “International Style” and the raw power of the industrial age.

The narrative of the Ruan Center is famously “rusty.” The tower is clad in Cor-Ten steel, a material designed to weather and oxidize over time, creating a deep, earthy protective layer of rust. This gives the building a distinct dark-brown hue that contrasts sharply with its glass-walled neighbors.

• The Business Pulse: For decades, the Ruan Center has served as the command center for the Ruan Transportation Management Systems, anchoring the city’s historic connection to the logistics and shipping industries.

3. The Reborn Classic: Des Moines Marriott Downtown (365 Feet)

Taking the third spot is the Des Moines Marriott Downtown. At 33 stories, it stands as the tallest hotel in Iowa. Completed in 1981, this tower tells the story of the city’s commitment to the convention and tourism industry.

While its exterior is a straightforward example of late-20th-century functionalism, its impact on the skyline is significant. It acts as a visual bridge between the historic Court Avenue district and the modern corporate towers of the northern downtown core. Its height ensures that guests have a front-row seat to the city’s evolution, offering views that stretch from the State Capitol to the Des Moines River.

4. The Financial Pillar: Financial Center (345 Feet)

Directly across from the Ruan Center sits the Financial Center, a 25-story tower completed in 1973. This building is a masterclass in the “Modernist” aesthetic of its time, featuring a sleek, vertical-ribbed facade that emphasizes its height.

The narrative of the Financial Center is one of stability. As one of the earliest “skyscrapers” to break the 300-foot barrier in Des Moines, it signaled the city’s transition from a regional market to a major financial player. Its presence helped establish the “Corporate Woods” feel of the downtown central business district.

5. The Plaza: A Residential Landmark (340 Feet)

Rounding out the top five is The Plaza, a 25-story residential and office hybrid completed in 1985. The Plaza represents the narrative of “Urban Living” in Des Moines long before it was trendy.

With its distinctive white facade and balconies overlooking the city, it remains one of the most prestigious addresses in town. It stands as a reminder that the skyline isn’t just for insurance executives and bankers—it is a place where people call home, watching the sunset over the Iowa State Capitol from their living rooms.

The Des Moines Skyline Rankings at a Glance

The “Golden” Outlier: The Iowa State Capitol

While not a skyscraper in the modern sense, no narrative of the Des Moines skyline is complete without mentioning the Iowa State Capitol. Standing on a hill east of the Des Moines River, its central dome—covered in 23-karat gold leaf—reaches a height of 275 feet.

By law, no building in the city was allowed to be taller than the Capitol for much of the early 20th century. While that rule has long since been surpassed by the giants of industry, the Capitol remains the aesthetic and spiritual anchor of the city. Its four smaller domes and grand central spire provide a historic counterpoint to the sharp angles of the downtown towers.

The Future Narrative: Expansion and Infill

The Des Moines skyline is currently undergoing a “Horizontal and Vertical” evolution. While 801 Grand remains the ceiling, new developments like the Blackbird Tower proposals and the expansion of the EMC Insurance campus suggest that the city’s appetite for height remains.

However, the current trend is “Infill.” The narrative is shifting toward 10-to-15-story mixed-use buildings in the East Village and the Western Gateway. These buildings may not break height records, but they are adding “visual density” to the city, creating a more continuous and vibrant urban fabric.

Conclusion: A Skyline with Soul

The tallest buildings in Des Moines are more than just glass and steel; they are monuments to Iowa’s work ethic and its quiet, steady growth. From the “Rusty” Ruan to the “Copper” 801 Grand, each tower represents a different era of the city’s ambition. Whether you are viewing the skyline from the Principal Riverwalk or flying into the Des Moines International Airport, these buildings serve as a proud reminder that in the heart of the Midwest, the sky is never the limit.
