The cathedral is the mother church for about 500,000 members in 144 parishes and missions in the region. Its spires reach 210 feet and the vaulted ceiling inside the cathedral itself reaches an apex of 68 feet. The four main bells are rung before and after the 10:30 a.m. Mass on Sunday and on special occasions. The stained glass windows on the west spire depict the symbols of the four major prophets: Isaiah, Jeremiah, Ezekiel and Daniel; the east spire windows show the symbols of the four evangelists: Matthew, Mark, Luke and John.

The Cathedral was designed by Leon Coquard, Aaron Gove, and Thomas Walsh and was inspired by French Gothic architecture. It has a Gunnison granite foundation, Indiana limestone exterior walls and interior structural marble from Marble, Colorado. Special features such as altars, pedestals, and the pulpit, among other things, are made of Carrara marble from Italy. There is a Gothic vaulted ceiling.
