30 Places to Visit Before You Are 20

How many lists haven't we seen with things to do or places to see before you die? Like we'll spend the afterlife comparing notes. Better see them when you're young and they can change the way you live your life, right? There is nothing wrong with beaches and amusement parks, but once in a while a vacation can also be educational. Here is a list of 30 places I would recommend showing your kids before they're twenty - to educate them about the evil and atrocities humans can commit but also show the glimmering hope of justice, faith, democracy and a better world order. All of them in or near Europe - if you're living elsewhere I recommend making a similar list for that part of the world.
