Another St. Louis landmark my uncle highly recommended was the Cathedral Basilica of Saint Louis. He was right again! It was incredible! It seemed like every square inch of wall, floor, and ceiling inside was covered in mosaics. I’ve never seen anything like it in my entire life!
The impressive mosaics in the cathedral were installed from 1912 to 1988. They collectively contain 41.5 million glass tesserae pieces in more than 7,000 colors. Those in the main dome were done by exiled Polish artist Jan Henryk de Rosen and depicts Biblical scenes from both the Old & New Testaments.
