Cathedral-Basilica of Saint Louis King of France

The Cathedral-Basilica of Saint Louis, King of France, also called St. Louis Cathedral, is the seat of the Archdiocese of New Orleans and is the oldest cathedral in continuous use in the United States alongside the Royal Presidio Chapel in Monterey, California. It is dedicated to Saint Louis, also known as King Louis IX of France. The first church on the site was built in 1718; the third, under the Spanish rule, built in 1789, was raised to cathedral rank in 1793.

Saint Louis Cathedral is in the French Quarter of New Orleans, Louisiana, United States, on the Place John Paul II, a promenaded section of Chartres Street that runs for one block between St. Peter Street on the upriver boundary and St.
