The towering Cathedral of St. John the Baptist is one of Charleston's premier religious structures, and arguably one of its busiest. With daily mass, multiple Sunday masses, and a heavy schedule of calendar of events, this gothic chapel is likely to be occupied during any quiet tour or visit. Distinguished as the mother church of the Roman Catholic Diocese of Charleston, the unique and impressive structure belies a stormy history that involves not one, but two such magnificent chapels, that is sure to fascinate visitors or all denominations.
