The magnificent St. John Church was built in the late 1920s and is the largest Catholic church in the state. Located in Plaquimine, Louisiana, only 15 minutes from downtown Baton Rouge, the huge Roman Basilica style building is considered the purest example of Italian Romanesque architecture in the South. It features massive exterior columns matched by huge oak doors.
Inside, the long walkway to the altar is marked by more columns and intricate stained glass windows made in Germany. The balastrino altar, handsome campanile and portico, plus the use of marble for the altar and communion rail, add to the elegance of this great cathedral.
