I have found in Youtube this video whit Barcelona's pictures. Enjoy!

The Catedral(church) of Barcelona building during the Romanesque one but finally it was finished in the gothic one, that is the style that predominates. The outside is sober, only decorated with the vertical abutments. The door of San Ivo is a representative sample of the Catalan gothic call. The inner ships are almost to the same height, which gives the impression to be in a single enclosure. The lateral chapels have a superior gallery, which confers to the set greater luminosity and amplitude. Cimborrio is covered in the interior with a wood caissoned ceiling. The main facade is of recent construction (final of century XIX and principles of the XX), although based on a 1408 project. It is of great interest the access door from claustro to the cathedral and the chapel of Santa Lucia.
