Kennywood is an amusement park located in West Mifflin, Pennsylvania, a suburb of Pittsburgh. The park first opened in 1898 as a "trolley park" at the end of the Monongahela Street Railway. The park was purchased in 1906 by F. W. Henninger and Andrew McSwigan and thus began the Kennywood Entertainment company that has remained a closely held family business for over 100 years. This traditional amusement park still has structures and rides dating back to its opening and the early 1900s.
