Indiana's 56 Churches on the National Register of Historic Places

56 Indiana churches stand on the National Register of Historic Places among the 9,288 congregations in the state's directory. Marion County and Indianapolis lead with 6 listings, Allen County holds 4, and the rest scatter across the courthouse-square towns. The earliest entry is Mooresville Friends Church, listed May 12, 1975, a fitting start for a state whose early settlement ran heavily Quaker.

Saint Mary Catholic Church in Indianapolis followed in 1977 and Newburgh Presbyterian on the Ohio River in 1978. Indiana's register churches mark the state's three settlement streams: Quaker and Upland South congregations from the river, German Catholic and Lutheran parishes in the canal counties, and the Yankee Protestant churches of the northern grid.

When did Indiana churches enter the National Register?

Indiana listed 15 churches in the 1980s and 12 in the 1990s, the central wave, but its most distinctive number is current: 10 listings in the 2020s already, the strongest present-decade pace in this series alongside Florida. Indiana's preservation office is actively working through small-town sanctuaries now, and the register list is still visibly growing.

How this list was assembled

The list joins the Churches List directory (9,288 Indiana congregations as of June 11, 2026) against the National Park Service's National Register of Historic Places database by building location and name. 56 matches hold as of the snapshot date; the earliest Indiana church listing dates to 1975. 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.
