Cathedral Basilica of the Immaculate Conception

Archdiocese of Denver

Denver  +13038317010 

The Cathedral Basilica of the Immaculate Conception serves as the mother church for the growing faith community of more than 500,000 Catholics, in 144 parishes and missions spread throughout northern Colorado.

The exterior of the structure is made up of limestone from Indiana and granite from Gunnison, Colorado. The altar, statuary, and bishop's chair are all made of marble imported from Carrara, Italy. The seventy-five stained glass windows came from the F.X. Zetter's Royal Bavarian Institute of Munich.

The Cathedral was consecrated in 1921 and elevated to a minor basilica on December 25, 1979. On August 13 and 14, 1993, His Holiness John Paul II celebrated Mass at the Cathedral as part of the World Youth Day celebration held in Denver that year.
