Prost Builders built the new cathedral and undercroft in 1970 for the Diocese of Jefferson City. This uniquely designed cathedral has proven it can stand the test of time both architecturally and in the quality of our construction. The main floor serves as the cathedral with seating for 1,000 parishioners at the time of construction and the lower floor is a full-service undercroft that includes bathrooms, a kitchen, and a large dining room.
