23. St. Francis de Sales Oratory – The ‘Cathedral of South St. Louis’

Often called “The Cathedral of South St. Louis,” St. Francis de Sales Oratory is a hidden gem of Gothic Revival architecture in Missouri. Built in the early 1900s, this towering church features a 300-foot spire, elaborate stained glass, and one of the most exquisite carved wooden altars in the country. Though lesser known than some of St. Louis’s other landmarks, this historic church is a treasure for architecture lovers and those seeking a glimpse of old-world craftsmanship.
