Walking tour around the buildings from Santiago Calatrava: Prince Philip Museum, the planetarium (an IMAX cinema), the Umbracle (promenade with palm trees, bitter oranges, aromatic plants....), the Agora, and the Opera House Reina Sofia. This complex is called the City of the Arts and Science. We could visit the museum in order to see the temporary exhibitions about science and technology or the Opera House, during this tour, visitors could access the areas where opera and musical performances offered by Palau de les Arts each season take place. The Oceanographic is behind the City of the Arts and Sciences and has nothing to do with the City of the Arts and Sciences, it is another project designed by the architect Felix Candela. The visit to the City of the Arts and Sciences is an outdoor tour, and does not include entrance fees. If you wish to access the Reina Sofia Opera or the Principe Felipe Museum or even the Oceanographic Park, visitors can purchase tickets directly there.
