Museu Nacional D’Art De Catalunya

The bus ride here is notable as it takes you through a super charming winding road to get there. The building is incredible and the views you get from outside of it are as well. They have an excellent collection of art (lotssss of romanesque murals)! And, a really good gift shop with loads of cool prints/books (and my fav, seeing books I love translated into Catalan). A must see—for a reason!
