St. Louis, Missouri, USA
Cathedral Basilica of St. Louis
Home to the largest mosaic collection in the Western Hemisphere, covering 83,000 square feet of interior surface.
From the outside it looks like a solid Romanesque church, handsome but restrained. Then you walk through the doors and your jaw drops. Every surface above eye level is covered in mosaic — 41.5 million glass tesserae in greens, blues, golds, and deep reds covering the domes, arches, lunettes, and vaults. It took seventy-five years to complete. The main dome shows scenes from the life of St. Louis IX, the French king who became a saint. The sanctuary mosaics depict Christ in glory with such intensity of color that the whole apse seems to glow. Side chapels tell the history of the Catholic faith in the Mississippi Valley, from French missionaries to German and Irish immigrants. The mosaics aren't ancient — most were installed between 1912 and 1988 — but the craftsmanship rivals anything in Ravenna or Istanbul. The lower church holds a small museum tracing the mosaic installation with photographs of the artists at work on scaffolding.
Diocese: Archdiocese of St. Louis
Style: Romanesque Revival and Byzantine
What to See
Sit in a pew and work your way around the ceiling with your eyes — rushing through does this place no justice. The sanctuary apse mosaic of Christ in Majesty is the centerpiece. The narthex mosaics depict the history of Catholicism in St. Louis, including the arrival of French missionaries. Side chapel mosaics honor various saints and biblical scenes. The lower-level museum shows photographs of the decades-long installation process and lets you see tesserae up close. Free guided tours are offered and highly recommended — the docents point out details you'd never catch on your own.
