Highland Park has several landmark structures listed in the National Register of Historic Places, notably the Willits House, by Frank Lloyd Wright. In addition to several houses designed by Wright, the National Register lists homes designed by prominent architects including John S. Van Bergen, Howard Van Doren Shaw, Robert E. Seyfarth, and David Adler. Landscape architect Jens Jensen lived in Highland Park and designed a number of projects in the community that are listed on the register. Highland Park has several attractions including a vibrant downtown shopping district and Ravinia Festival, the summer home of the Chicago Symphony Orchestra and a nightly music program covering classical, blues, jazz and rock. The Ravinia Festival is located in the Ravinia District, originally an artists' colony which still retains much of its early character and architecture.
