Saint Louis Roman Catholic Church, Buffalo

Saint Louis Roman Catholic Church is the oldest Catholic parish in Buffalo. It was the first Catholic church built in Buffalo, and holds the title of "Mother Church of the Roman Catholic Diocese of Buffalo".

The parish was established January 5, 1829 with land contributed by Louis Stephen LeCouteulx de Caumont, a French nobleman. The first church, constructed of logs, was completed in 1831. The congregation was largely French, German and Irish.

The current church was constructed in 1889. The historic Gothic Revival third church is laid out in a Latin-cross floor plan and features a 245 ft octagonal Medina sandstone steeple with a Seth Thomas clock. Above the steeple rests a 72 ft pierced spire; reputed to be the tallest open-work spire ever built completely of stone (without reinforcement) in the U.S. Inside the church is a 1903 Kimball Organ, which is located in the choir loft.
