Professional sports are also well represented in Indiana. One of Indiana's oldest and most famous sports venues is the Indianapolis Motor Speedway. Its first race was May 30, 1911. Indiana's natural heritage has benefitted from private and public attention over the years. In 1916, Indiana began its state park system under Richard Lieber, who became a leader in the national conservation movement.
Private organizations help to preserve many natural areas in Indiana.
There are 4 national areas designated for their special importance. Such areas are also important for recreation for Hoosiers and tourists. Since the 1960s historic preservation organizations have united to identify and save important elements of the built environment and archaeological sites of Indiana's prehistory. Through state and federal government efforts, Indiana sites have been identified and given protection as historic sites in the State Register and the National Register of Historic Places. The state has also designated 16 historic sites under the State Museum system and provided for military monuments under the War Memorials Commission to honor Hoosiers who have died in combat.
