The oldest amusement park in the United States, Kennywood was built in 1898 and is still in full operation today. It was declared a National Historic Landmark in 1987, not only because of its 19th century construction, but also because it stands on the land where the Battle of the Monongahela (1755) took place (a battle that resulted in British general Edward Braddock being mortally wounded and the U.S. army was under the direction colonel George Washington).
From its humble beginnings of a trolley park/ picnic area to the well established destination it is today, Kennywood has made a name for its self in the amusement park industry as well as history, and it doesn't seem to be stopping anytime soon. With over 46 rides/attractions and a bountiful history, there is no doubt that people of all ages can enjoy this wonderful theme park. Feature rides include the Exterminator, the Black Widow, the Pittsburgh Plunge, Thunderbolt, Raging Rapids, and the Whip.
