The Terror Museum in Budapest, Hungary.

Really a museum unlike anything - if you are expecting something to put you in a good mood, this is not your place. However, it does a fantastic job at showing the cruelty that took place in Europe during the iron curtain.

It will leave you thinking for the rest of your day about what really happened to people during that time.
