Designed by Donaldson and Meier and 1921, this Roman Catholic church in Southwest Detroit has a stunningly ornate sanctuary with coffered ceiling, arches and columns, painted panels, and much more.

It’s the only church we’re putting on this list but there’s many more whose interiors are worthy of note: Ste. Anne de Detroit, Sweetest Heart of Mary, St. Joseph, Woodward Avenue Presbyterian, and Historic First Congregational, to name a few.

How do you begin to describe something this gorgeous? Designed by Albert Kahn, “Detroit’s largest art object” has a stunning marble exterior that’s arguably exceeded by its interior. The most impressive section of the building is surely the main arcade, with its vibrant frescoes, barrel-vaulted ceiling, gold panels, marble pillars, and countless other decorations.

Had the Fisher Theatre not been renovated, removing many of the ornate elements, it would have made this list as well.

While not as opulent as its neighbor across West Grand, the former General Motors Building, also designed by Albert Kahn, has a beautiful interior as well. The long barrel ceiling in the arcade with panels of various designs and materials is especially impressive.

Designed by renowned American architect Cass Gilbert, the Main Branch of the Detroit Public Library has a wonderful interior with marble walls, grand frescoes, and ornate ceiling panels.

The Wayne State University–owned building in Midtown designed by Albert Kahn gets included on this list for its lobby alone, which has a jaw-dropping barrel ceiling, marble floors and walls, gold clad elevators, and wonderful Art Deco fixtures.

Many rooms in the DIA are among the finest in the city, whether it’s the light-filled Kresge Court, C. Howard Crane–designed theater, or the numerous galleries. But none compare to Rivera Court and the 27 painted panels that make up Diego Rivera’s Detroit Industry Murals.

There are too many stunning features, both inside and out, of this Neo-Gothic masterpiece designed by George D. Mason to mention—it’s the largest Masonic temple in the world, after all. But each of the theaters, rooms, and lobbies, with its various nods to world cultures (Egyptian, Byzantine, Italian), is a site to behold.

The exterior of Orchestra Hall is rather plain—the interior, however, is magnificent. There’s dozens of painted panels and archways, including the grand proscenium arch surrounding the stage, as well as corbels, medallions, and much more.

The shockingly opulent theater designed by C. Howard Crane is arguably one of the most beautiful venues in the world. It contains an eclectic and ornate mix of decorations in Egyptian, Far Eastern and Indian styles.

If you can gain entry into the private, Albert Kahn–designed club, it’s well worth it. The impressive lobby has an ornate ceiling with decorate panels and wood-paneled walls, and the main dining hall is just as lovely with its pained coffered ceiling.

The most recently constructed building on this list is probably its most controversial entry. But the Bedrock Detroit–owned One Campus Martius is on here because of its glass-filled lobby with skylight atrium and multi-floor waterfall—it’s a pretty impressive sight.

Opened in 1929 and designed by Wirt C. Rowland of Smith, Hinchman & Grylls, the “Cathedral of Finance” definitely stands out in the skyline. But the jaw-dropping lobby and banking hall—with its three-story, Aztec-themed design made of Rookwood Pottery and Pewabic Tile, metal screen with Tiffany-clock inlay, and Michigan commerce mural—make it arguably the most beautiful interior in the city.
