Kennywood Park, designated a National Historic Landmark in 1987, began in 1898 when a picnic grove on Anthony Kenny's farm here was leased to the Monongahela Street Railway Company for an amusement park linked to Pittsburgh by its trolley line. Sold to private interests in 1906, the park survived the Depression, recessions, and two World Wars. Years after most other trolley parks had closed, Kennywood was still thriving.
