The Basilica of Saint Mary’s nave is a masterpiece of church architecture. It is defined by arched, stained glass windows and a barrel vault measuring 138 feet. The marble altar is encased in a baldachin suspended by four Doric columns. Soaring above is a dome plus lantern. Together they reach a height of 200 feet. These are a few of the features earning the pro-cathedral a listing by the U.S. Register of Historic Places.
