In 1913, Michigan Central Station was the largest train station in the world. Today it is literally just a shell of it's former glory. And although it is listed on the National Registry of Historic Buildings, it stands on the verge of being demolished.
Like many of the beautiful and architecturally significant buildings in Detroit, the station fell victim to abuse and neglect when the city began to deteriorate. These photos below show how the train station looks today. I find it completely heartbreaking.
