Detroit’s Cathedral of Finance
Downtown Detroit’s Financial District has plenty of towers, but nothing else looks quite like this one. The Guardian Building climbs 40 stories into the sky, and its outline gives it away before you even reach the door.
A tall tower rises above a wide, nave-like base, and the whole structure reads like a great cathedral. People started calling it the Cathedral of Finance for that reason.
Step past the orange brick facade, though, and the real show is waiting inside.

Born in Detroit’s Roaring Twenties
The building went up fast, finished in 1929, the same year the stock market crashed and took much of the country down with it.
The Union Trust Company built it as their flagship headquarters, and they hired architect Wirt C. Rowland of Smith, Hinchman and Grylls to design it.
Crews cleared a full city block downtown just to make room for the tower.
Six decades later, in 1989, the National Park Service named it a National Historic Landmark, the highest honor the agency hands out.

Spot the Famous Guardian Brick
You can spot the Guardian Building from blocks away because of its skin.
The exterior wears custom orange bricks made just for this project, a warm tangerine shade you won’t find on any other skyscraper in the country.
The brickmaker liked the color so much that afterward, the company started selling it under its own name, Guardian brick.
Granite and stone form the base beneath all that orange, grounding the tower before it climbs 40 stories toward the sky.

Color Made to Catch Your Eye
Architect Wirt Rowland had strong opinions about buildings.
He believed a structure had to grab your attention right away, so instead of plain gray stone, he covered the Guardian Building in colored brick, stone and terra cotta.
Near the top, he had the terra cotta detailing made oversized on purpose, so drivers and pedestrians far below could still make out the patterns.
Rowland once said color carried a vital power to catch the eye, and this building proves he meant it.

Step Into the Three-Story Lobby
The outside only hints at what waits for you inside.
Walk through the doors and you land in a lobby that soars three stories overhead, vaulted like a church nave and covered in color from floor to ceiling. Most people stop cold the first time they look up.
The design mixes Native American, Aztec and Arts and Crafts influences into one space, and the craftsmanship stretches across nearly every surface you can see, from the tile underfoot to the painted ceiling above.

Handmade Tile From Michigan Kilns
Look up in the entrance and you’ll find a dome covered in colorful Rookwood tile, packed with bold geometric patterns and rich, saturated color.
Pewabic Pottery, a Detroit company, made the tile that fills the lobby’s vaulted ceiling, working closely with Rowland to get the designs right.
Artist Mary Chase Perry Stratton collaborated with the architect on the patterns you see today. Together they turned a functional ceiling into one of the most photographed spots in the whole building.

A Glass Mosaic Over the Lobby Desk
Above the main lobby desk hangs a mosaic you won’t be able to walk past without looking twice.
Michigan artist Ezra Winter designed the glass artwork, and it’s usually one of the first things people notice once they step inside. The mosaic pictures a pine tree alongside a message tied to the building’s purpose.
Small glass pieces catch the light differently depending on where you stand, which is part of why visitors tend to linger under it longer than they planned.

The Painted Banking Hall
Ezra Winter’s work doesn’t stop at the mosaic. He also painted a grand mural inside the old banking hall, one that highlights Michigan industries like farming, mining and manufacturing side by side.
Above the mural, the ceiling is hand-painted canvas stretched over horsehair, a trick that softened the sound of a busy banking floor decades ago.
The hall shows how the building balances art with function, since even the acoustics got the same careful attention as the artwork.

Sculptures Guarding the Front Door
Before you even step through the Griswold Street entrance, two stone sculptures greet you on either side of the door.
Detroit sculptor Corrado Parducci carved them, and they represent Safety and Security, fitting themes for a building that once housed a bank.
Above the entrance, a semi-circular tiled dome crowns the doorway, matching the color and pattern you’ll find once you’re inside.
The details start before you’ve even crossed the threshold, which tells you what the rest of the building has in store.

A Screen Made of Rare Metal
Inside, a large ornamental screen separates the lobby from the old banking hall, and it’s not made from the brass or bronze you’d expect. Rowland chose Monel metal instead, a rarer and more durable choice for the era.
A clock designed by Tiffany sits right in the center of the screen, drawing the eye as you pass through.
Architects took notice of Rowland’s choice, and the same Monel metal later showed up in New York’s Chrysler Building.

Marble Shipped in From Three Continents
Marble shows up everywhere you look once you start paying attention.
Italian Travertine lines the steps and walls throughout the lobby, while deep red Numidian marble, imported all the way from Africa, adds a bolder splash of color in other spots.
Even the corridors and restrooms get the treatment, finished in marble shipped in from Tennessee.
All that stone adds warmth to a building that could have felt cold and institutional, and instead feels rich at every turn.

A Temple Built by Michigan Hands
None of this happened by accident or by outside hands.
About 40 artisans worked on the murals, tile and mosaics that fill the building, and Michigan architects, contractors and craftsmen built the entire structure from the ground up.
People around Detroit often call it a temple of Michigan skill and pride, and once you’ve walked through it, that description makes sense.
Every surface, from the orange brick outside to the marble underfoot, reflects the hands that built it.

Visiting the Guardian Building in Michigan
The Guardian Building sits at 500 Griswold Street in downtown Detroit, in the heart of the Financial District and close to other downtown sights.
The lobby stays open to the public and costs nothing to walk through, so you can wander in, look up at the tile dome and take your time with the mosaic without paying a dime.
If you want more than the lobby, local tour companies run guided, behind-the-scenes visits that get you into areas most walk-in visitors never see.
