Welcome to the National Art Museum of Catalonia, which sits on the hill of Montjuïc in Barcelona. You are standing at the Palau Nacional, a monumental palace that was built as the main venue of the 1929 International Exposition. Before you even step inside, the building does a lot of the talking. There is a grand outdoor staircase, a large cascade of water in front of it, and big, ceremonial halls waiting behind the doors. The palace now houses a collection that traces the artistic history of Catalonia, from Romanesque art to modern art. In this guide we will look at how the palace came to be, how a museum eventually moved into it, and which masterpieces and fragments of medieval Catalonia you can meet inside. We will also look at the neighborhood of exhibition buildings around it. If you are arriving by public transport, the metro stop at Espanya, on lines one and three, is the one to use. If you come by car, there is a paid municipal car park next to the museum. Now, let's start where the story starts: with a world's fair.
