Address: 1017 N LA Salle Dr Zipcode: 60610 Phone Number: +1 312 664 5485 The first Greek Orthodox congregation in Chicago built this cathedral. It is modeled after the Cathedral Church in Athens, Greece. The exterior is done in a Renaissance-Byzantine style with a dome rising from the center of the rectangular building. In 1938, a number of stained glass windows were added that depict various saints from the Eastern Church. The light from the windows warmly illuminates the rich interior of the main auditorium.
