The Guardian Building was built in 2 years and opened in 1929, and was the tallest masonry building in the world at the time. The orange bricks were made especially for it. The rare back and red marble in the lobby were mined in Belgium and Africa. It was opened to the public for the first time in 2003, and is my favorite building in Detroit. It’s a stunning architectural reminder that Detroit in its heyday was the most beautiful American city, and that we have our own majestic standard as we return Detroit to its former glory.
