What's the most shocking thing you've seen in another country?

For me it was when I was around 10 years old, I was in China and came across a gruesome display in a park. There was a tunnel with artwork depicting the historical and brutal torture and executions of Christians, probably from the 1800s. They were gory scenes of many people being chopped into pieces, being boiled alive, etc.
