St. Thomas Church and Convent
Why it's listed
St. Thomas the Apostle Church and its neighboring convent occupy a corner at Kimbark and 55th Streets in Chicago. The convent, finished in 1919, and the church, completed in 1922, were designed by Francis Barry Byrne, who trained in Frank Lloyd Wright's Oak Park studio. The church is notable for broad, undecorated brick walls, herringbone brickwork, and a chevron motif in terra cotta around windows, copings and entrances, with sculpted angels at the main portal. Inside, the ceiling appears to float without support, and the sanctuary flows into the nave. The convent has a Spanish appearance and a tiled hipped roof, yet keeps low halls and wood-lined windows that recall Wright. Together the buildings show Byrne moving away from the Prairie School toward his own style. The church was an early statement of that style on a major building, and its integrated sanctuary anticipated later liturgical changes by about forty years. Exterior ornament was largely by Alfonso Iannelli.
Significance in brief: The nomination argues the two buildings, standing a few feet apart, represent two phases of Byrne's career: the convent a tentative departure from the Prairie School, the church the first positive statement of his personal style on a major non-domestic building. The church also integrated the sanctuary with the nave decades before liturgical reforms did so. It is described as a milestone in Byrne's work and an important prototype in church architecture.

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.
