Louisiana's 57 Churches on the National Register of Historic Places

57 Louisiana churches stand on the National Register of Historic Places among the state's 7,372 directory congregations. Orleans and Rapides parishes lead with 7 listings each, and the earliest entry is the St. Alphonsus-St. Mary's Assumption complex in New Orleans, listed August 12, 1971 — twin Irish and German Catholic churches built across one street in the 1850s by rival immigrant congregations of the same archdiocese.

The register list reads as a map of Louisiana's layered settlement: French and Spanish colonial parishes along the rivers, Anglo-Protestant churches in the northern hill parishes, and the Episcopal churches of the railroad towns, like Grace Memorial in Hammond (listed 1973).

When did Louisiana churches enter the National Register?

Louisiana's listing wave peaked early and hard: 23 churches entered the register in the 1980s alone, 40 percent of the state's total, driven by comprehensive New Orleans and plantation-country surveys. The pace settled to 9 in the 1990s and has run 5 to 7 per decade since, with recent listings extending into Creole and Black Baptist church history.

How this list was assembled

The list joins the Churches List directory (7,372 Louisiana congregations as of June 11, 2026) against the National Park Service's National Register of Historic Places database by building location and name. 57 matches hold as of the snapshot date; the earliest Louisiana church listing dates to 1971. A register listing covers the building, not the congregation, and some listed buildings house congregations younger than the walls. Corrections are applied through the corrections page.
