 Visually, it was intended to bridge the gap between the traditional Roman Catholic cathedral and the typical Protestant church buildings of the late 19th century and early 20th century.The building was originally intended to be 20 feet longer, but due to widening of LaSalle Street, the layout had to be altered; this is believed by some to be the reason for the unusually steep choir loft.From floor to the false acoustic ceiling is 68 feet, and the structural ceiling is 10 to 15 feet above that.
