The Xiengkuane Buddha Park in Vientiane, Laos, is filled with statues of all shapes and sizes. At one end, a tower represents heaven. At the other, this bowl and flames above are the embodiment of hell. You can climb through it, visiting the 3 different levels of hell, on your way to the top.
If you find yourself in Laos, it's well worth a visit. I'd say it's the strangest and coolest place I've visited in ages,
