When we walked towards the Cathedral Basilica of St. Louis, we didn’t have our hopes up. I mean, yeah, it’s a big church, cool. But as we stepped through the doors and found ourselves face to face with one of the largest mosiac installations in the Western Hemisphere,we knew we were witnessing something special. Completed in 1914, and comprised of 41.5 million glass tesserae pieces, your jaw is guaranteed to drop, as you witness the largest mosaic outside Russia. Take our word for it, it’s worth the trip.
