Notre Dame Academy and Convent, Omaha

The Notre Dame Academy and Convent is located at 3501 State Street in the Florence neighborhood. It is significant for its ethnic association with the Czech population in Nebraska as the only school and convent of the Czechoslovakian School Sisters de Notre Dame (this is not the same order as the School Sisters of Notre Dame) in the United States. The building was listed on the National Register of Historic Places in 1998.

Influenced by the 1898 Trans-Mississippi Exposition, Omaha architects Matthew Lahr and Carl Stangel designed the E-shaped convent and school in 1924. It was constructed in phases over the next twenty-six years, all complying with the original design. It was designed in the late Italian Renaissance Revival style. Notre Dame Academy was sponsored and staffed by the Notre Dame Sisters from 1926 through its merger with Rummel High School to form the present Roncalli Catholic High School in 1974.
