Blessed Trinity Roman Catholic Church Buildings
Why it's listed
Blessed Trinity Roman Catholic Church Complex sits in a residential neighborhood of northeast Buffalo, fronting LeRoy Avenue. Its centerpiece is a church built between 1923 and 1928 to designs by Chester Oakley and Albert Schallmo, inspired by the churches of northern Italy. The building follows the twelfth-century Lombard-Romanesque style, with an octagonal clerestory, ribbed and barrel vaulting, and a terra-cotta tile roof. Its walls are handmade, unmolded brick laid in herringbone patterns, produced in New Hampshire with medieval methods. Colored terra-cotta decoration and more than two thousand symbols, paintings and sculptures form a plan of Christian iconography devised by Reverend Thomas Plassman. A cloister links the church to the 1914 parish house, and the 1907 church-school building with its mansard roof stands nearby. The complex was listed for its architecture, its craftsmanship and its richness of detail, unusual for a working-class parish and unique in Buffalo.
Significance in brief: The church is presented as one of the purest examples of twelfth-century Lombard-Romanesque architecture in the United States and the only pure example in Buffalo. It is notable for its handmade medieval-style unmolded brick, extensive colored terra-cotta decoration and a comprehensive Christian iconography plan with over two thousand symbols and pictures.

What listing means for this property
Religious properties are listed for their architectural or historical significance, not their religious use. Listing is honorary and does not restrict the congregation's use of the building. The federal rehabilitation credit is generally unavailable unless part of the building is income-producing; some state programmes and preservation grants do cover religious buildings. Federal funding or permits trigger Section 106 review.
