The First National Building is a skycraper and class-A office center in downtown Detroit, Michigan. Completed in 1930, the structure rises 25 stories and includes two basement levels, occupying an entire block along Cadillac Square. Located within the Detroit Financial District, the tower's main uses are for offices and retail. It was constructed primarily with limestone. The building was designed by Albert Kahn in the Neoclassical architectural style. It has an unusual "Z" shape, designed so that most offices would have natural light and ventilation. The building is located across the streets from Cadillac Tower and Comerica Tower, and stands next to the Vinton Building. It is 341 feet tall. Three-story Corinthian columns surround the building at the second floor. The space behind the columns originally housed the main banking hall; however, this space was divided for offices during a renovation. The building also houses a parking garage in the west tower, which is accessible from Bates Street. The original cornice was removed in the late 1970s, and the parapet of the building covered with corrugated aluminum. Wikipedia [ - ]
