where the livery, and all the other small companies were, is now a couple skyscrapers. Probably the wood buildings were accidentally burned down, or bought up and replaced with newer company and corporate buildings as downtown became less frontier and more profit driven because in the roaring 20s, the area became known as the financial district
the whole block is now just two buildings, one is the Guardian Building, built in 1928-29 in the art deco style
The building has been designated a National Historic Landmark, and is owned by Wayne County, Michigan and serves as its headquarters.
The exterior of the Guardian Building is faced with stunning tangerine colored bricks resting on a granite base. Polychromed terra cotta on the upper stories was purposefully over-scaled to be seen by motorists on the street below.
Designed by Michigan architects, erected by Michigan contractors, and built by Michigan artisans: the Guardian Building is virtually a temple of Michigan commerce and ingenuity. The Griswold Street entrance is crowned with a semi-dome lined with symbolic custom tiles, and the main lobby has a large glass mosaic as well as the spectacular mural in the original banking hall.
