Montjuïc has one of the most iconic views of the city: The Palau Nacional. This building contains the Catalan National Museum (MNAC) and is very well known around the city for the big city lights that can be seen during the evenings. The building was the main pavilion built for the World Fair of Barcelona of 1929. The opening ceremony, chaired by the king Alfonso XIII, took place in its oval room, to this day still used for public events. It became a museum in 1934, and nowadays strolling around its rooms means walking through thousands of works and centuries of art history.
