Grand Army of the Republic Building
Starting the list is one of the most renowned historical sites that visitors will find in the city: the Grand Army of the Republic Building. Found on Grand River Avenue, this landmark is considered Detroit's castle, which is now home to two restaurants as its beautiful interior (and exterior) simply couldn't go to waste!
The gorgeous building was intended to be a hangout spot for Detroit's civil war veterans, even though it looks as if it was built to protect people from invaders. It has been an iconic Detroit landmark since the 1800s and was designed by a talented Detroit architect, Julius Hess, who embraced the Richardsonian Romanesque style.
