Cathedral of St. John the Baptist
One of the churches that has open doors to the public in Charleston, SC, is the Cathedral of St. John the Baptist. Staggering high over Charleston, the structure is worth stepping in alone just to view the magnificent stained glass windows from the inside. The stained glass line the sides of the cathedral on both the bottom floor and top level parallel with the balcony and end with a copy of the Last Supper at the front of the church.
Location: 120 Broad St.
