The capital cities. If you want authentic Europe, find the weird local festivals where people chase cheese down a hill or celebrate local culture or something. That’s real Europe. Fuck the big cities and their galleries and museums.

These are a few things off the top of my head mostly northern and western Europe because it’s what I’m familiar with. Also if you want to see something bizarre, go to Finland on free bucket day. But seriously Europe is full of unusual things to do. Or you could go to yet another gallery and pretend to be interested in paintings.
