Nicknamed the “Cathedral of Commerce,” the Guardian Building is one of the most expressive Art Deco skyscrapers ever built. Built in 1928 and finished in 1929, the building was originally called the Union Trust Building and is a bold example of Art Deco architecture, including art modern designs. The main frame of the skyscraper raises 36 stories, capped by two asymmetric spires, one extending for four additional stories.
Opened in 1929, the Guardian Building is one of Detroit’s
most magnificent art deco skyscrapers. Designated a National Historic Landmark
in 1989, the Guardian Building was designed by Wirt C. Rowland of the leading
Detroit architecture firm Smith, Hinchman & Grylls. The cathedral theme is
emphasized on the exterior by the two towers at each end of the building
connected by a somewhat lower navelike block. The theme is played out in the
interior with the tall banking lobby designed as a nave with side aisles. A
specially formulated orange brick, known as Guardian brick, clads the steel
frame. Brilliantly colored terra-cotta, glazed tile, and gold-stained glass and
metal decorate it inside and out. The Guardian Building was the world’s tallest
masonry structure when it was completed.
Originally named the Union Guardian Building, this building
was created for the Union Trust Co. when it required more space after a merger
with the equally huge National Bank of Commerce. By the time the building was
completed, Union Trust had bought up several other banks and become the
Guardian Detroit Union Group, which held 40% of Detroit’s banking resources.
But the Great Depression hit Detroit — and the bank — hard. In 1932, the bank
went into receivership as the New Union Building Corp.
During World War II, the building was used as a command
center for the Army as it coordinated ordinance production. After the War and until
the present day , the building has served various tenants as an office building
in downtown Detroit.
