This weird tourist attraction is located in Thailand.
It was meant to describe the depict naraka (Buddhist hell).This hell garden is the biggest garden in whole Thailand.
At the entrance there is a sign that reads "welcome to hell".In the middle of the garden there is another sign that reads "If you meet the Devil in this life, don't postpone merit-making which will help you to defeat him in the next life."
Hell garden reflects in vulgar details the punishments that might be in the store that transgress in life.
