St Louis, host of the 1904 World Fair, created an impressive collection of architecture to capture the heart of the world and the spirit of America a century ago. One example is the Cathedral Basilica of Saint Louis, the world’s largest mosaic covering 83,000 square feet with 41.5 million pieces of glass tesserae. The mosaic was finished in 1988 and employs multiple artistic styles, the signature of a modern cathedral.
