I have lived in Denver since 1987 and The Cathedral is by far the most beautiful and inspirational of all the churches that I have been to. It is a small church, yet it is very welcoming and your heart feels so large when you are praying in it. This is one on Denvers most precious landmarks and by far the most beautiful church in town, maybe in all of Colorado.
Pros: beautiful, inspirational, spiritual
Cons: need more parking, crowded, right on Colfax
