One of the best examples of French architecture in the country, this triple-spired cathedral is dedicated to Louis IX, the French king sainted in 1297; it's a most innocuous bit of Gallic heritage in the heart of an American city. In addition to hosting black, white and Creole Catholic congregants, St Louis has also attracted those who, in the best New Orleanian tradition, mix their influences, such as voodoo queen Marie Laveau.
The present cathedral was dedicated on Christmas Eve, 1794, and awarded the rank of minor basilica by Pope Paul VI in 1964.
