The Avery Coonley School in Downers Grove has been added to the National Register of Historic Places.
The school, at 1400 Maple Ave., was added to the list because of its "unique design and features that have exerted a long-lasting influence on schools throughout the country," said Robert Coomer, director of the Illinois Historic Preservation Agency.
The school was built in 1928-1929 to be part of the Progressive Education Movement centered in Chicago.
It is built in the Prairie School style of architecture, and was landscaped by well-known Danish architect Jens Jensen.
The school features easy access to the outdoors, child-sized classrooms with homey touches such as draperies and fireplaces, primary classrooms on the ground floor and separate science labs.
