35. Craco, Italy
Founded in the 8th Century, the hilltop town of Craco had a rough go of things for several centuries (give or take), falling victim to earthquakes, wars, and the Black Plague. The final straw was a 1963 landslide, which forced all remaining residents to evacuate the city. The original city sits in a state of slow decay, although it’s still a popular site for visitors. There are even a few annual religious festivals held in Craco from May to October, while off-season tourists can enjoy the city ruins and cliffside views.
36. Six Flags (formerly Jazzland), New Orleans
The Six Flags in New Orleans was one of the architectural casualties of Hurricane Katrina. The park was flooded, and the water remained stagnant there for several weeks. The park is currently a pastel wasteland, full of skeletal roller coasters, upside-down concession stands, and terrifying decapitated clowns.
