Uncovering the 7 Most Unique Features of Detroit's Art Deco Masterpiece

The Guardian Building is not merely an Art Deco skyscraper; it is a revolutionary work of architecture that broke from tradition. Architect Wirt C. Rowland sought to create a building that was uniquely American, moving away from European influences, and the result is a breathtaking blend of vibrant color, cultural symbolism, and intricate detail.

1. It's One of the Tallest Brick Structures in the World

While many skyscrapers rely on steel and concrete for their exterior cladding, the Guardian Building is famed for its extensive use of brick and terracotta. It remains one of the tallest brick-clad structures globally. The exterior is a stunning mosaic of colorful brick, primarily a warm orange-red, contrasted with colorful terracotta tiles that give it its distinctive, vibrant appearance.

2. The Lobby's "Rainbow" Palette Was Revolutionary

In the 1920s, most commercial buildings were designed with muted, conservative colors. Rowland, however, embraced a radical, vibrant palette. The interior is famous for its extensive use of Pewabic Pottery tiles (a local Detroit entity), Rookwood Pottery, and colorful marbles in shades of orange, yellow, red, blue, and green. This bold use of color is a defining characteristic of the Art Deco style, specifically the American Perpendicular style, and earned it the nickname "Cathedral of Finance."

3. The Three-Story Mural is a Hidden Masterpiece

The main banking lobby (now a public atrium) features a colossal, three-story mural painted by muralist Ezra Winter. The mural depicts the history of Michigan's economy and its natural resources, executed in a dynamic, stylized Art Deco fashion. It dominates the space and is a key feature that makes the building a must-visit landmark for architecture enthusiasts. The scale of this artwork is truly staggering and contributes significantly to the building's dramatic interior atmosphere.

4. Mayan and Native American Motifs Replace Classical Greek

Wirt C. Rowland deliberately rejected the classical Greek and Roman motifs popular in earlier architecture. Instead, he incorporated geometric patterns, chevrons, and abstract designs inspired by Native American and Mayan Revival architecture. This detail is evident in the striking bronze elevator doors, the intricate terracotta work on the exterior, and the stylized figures throughout the lobby, making the building uniquely American in its artistic expression.

5. It Was Originally Named After a Financial Powerhouse

When it opened in 1929, the building was called the Union Trust Building, built for the powerful Union Trust Company. Its original purpose was to be a symbol of the company's financial strength and the optimistic economic boom of the Roaring Twenties. Unfortunately, the Great Depression hit shortly after its completion, leading to financial restructuring and a name change to the Union Guardian Building, before eventually being shortened to the Guardian Building.

6. Wayne County is the Anchor Tenant and Owner

In a significant move for Detroit's revitalization, the Guardian Building was purchased by Wayne County in 2008 and currently serves as the primary location for many of the county's government offices. This transition secured the building's future as a functional, vital part of the city's civic life. Recent updates from late 2024 and 2025 confirm that the county continues to consolidate its operations in the building, including the relocation of more employees to save on operational costs.

7. The Vandalism Incidents Highlight Its Ongoing Public Presence

The landmark’s continuous public presence means it occasionally makes headlines for less celebratory reasons. In a concerning series of events reported in late 2024, two individuals were charged with vandalizing the historic structure. They reportedly used a slingshot to target the windows and doors of the building, an act that drew widespread media attention and underscored the need to protect this National Historic Landmark from damage.

The Enduring Legacy of the Guardian Building in Modern Detroit

The Guardian Building stands as a testament to Detroit’s architectural golden age and its ongoing urban renaissance. Its presence in the Financial District is a constant reminder of the city's ambition. Beyond its historical significance, the building serves as a public space, welcoming visitors to admire its spectacular lobby, which often hosts events and is a frequent backdrop for photography and film.

Its designation as a National Historic Landmark ensures its protection for future generations. For anyone visiting Downtown Detroit, a stop at 500 Griswold Street is essential. To truly appreciate the Art Deco movement, one must experience the towering, colorful brilliance of Wirt C. Rowland's masterpiece, a building that continues to guard the spirit and history of the Motor City.
