The church of St Thomas, the Apostle and Howard-Flaget House is a historic Roman Catholic church and home located at Bardstown, Nelson County, Kentucky. The church is a brick, cross-shaped plan with a round apse. It was designed by Baltimore architect Maximilian Godefroy and built 1813–1816. It closely resembles Godefroy's earlier St. Mary's Seminary Chapel in Baltimore, another Sulpician church. St. Thomas is the oldest Roman Catholic church in Kentucky and considered "The Cradle of Catholicism in Kentucky."[1]
St. Thomas Roman Catholic Church and Howard-Flaget House was listed on the National Register of Historic Places in 1976.
