The oldest surviving Catholic church in Louisiana's Acadiana region, established in 1776 and rebuilt in the current form in 1822. The church served both the French Creole community and the large population of free Black Catholics in the antebellum period — a demographic unusual in the American South and central to understanding Louisiana's complex racial history.
The current building is a modest but well-preserved example of early Louisiana ecclesiastical architecture. It sits about 1 km north of the main square and is open to visitors outside of Mass times.
