Six Flags Over Philadelphia

History
The park opened in 1980.

In 1989, Ninja was added.

In 1997, the Gotham City area was added to the park, featuring Batman: The Adventure, a B&M Batman clone, Joker's Wildcard, a relocated and renamed Roulette Wheel, and Gotham City Crime Wave, a Huss Top Spin.

In 2007, Wiggles World, now known as Kidzopolis, opened.

In 2014, the Metropolis area opened. The area was formerly a part of the Gotham City area that'd been split off from that area and rethemed to Superman. Gotham City Crime Wave, which was in the area, was removed during the off-season and replaced with Superman: Ultimate Flight

Entrance
The entrance is similar to Six Flags America and Six Flags New England's entrances, featuring a colonial America theme with statues of George Washington, John Adams, and Thomas Jefferson.
