What exactly turns an ordinary church into a cathedral—and why does it matter? Is it the soaring spires? The echo of centuries-old prayers? The hidden stories carved into stone and stained glass? Cathedrals aren’t just buildings; they’re time capsules, treasure chests, and spiritual landmarks all rolled into one. In this two-part series, we’re going on a globe-spanning adventure into the architecture, mystery, and beauty of some of the world’s greatest houses of worship. Based on my travels, we will explore everything from sanctuaries in South America to onion-domed marvels in Russia. Pack your curiosity—we’re about to step into places where history and holiness meet.
