When the Highland Park Ford Plant chugged to life in 1910, it was the largest manufacturing facility on the planet. Not content to have his base of operation be merely the largest, Henry Ford also made it the most efficient in 1913, when he installed an assembly line to make Model Ts. The building itself is unremarkable in large part because so many facilities were modeled after it during the decades that followed. Listed on the national register of historic places, the plant was designed by Albert Kahn, the most famous architect working during the advent of the modern industrial age. Today, the facility houses Ford archives and some cars, but is mostly empty. Parts of it are for sale and may soon house retail spaces and a coffee shop.
