The Palau Nacional (en: National Palace), situated in Montjuïc (Barcelona), is a palace constructed between the years 1926 and 1929 for the 1929 International Exhibition in Barcelona. Since 1934 it has been home to the National Art Museum of Catalonia. It was the main building of the exhibition, realised by Eugenio Cendoya and Eugene Henry Catà under the supervision of Pere Domènech i Roura, which disregarded the initial project proposed by Puig i Cadafalch and Guillermo Busquets. The palace’s Oval Room was host to the opening ceremony of the Exhibition, presided by Alfons XIII and Queen Victòria Eugènia.
The Palace has a ground surface of 32,000 m² and is constructed in a classic style of architecture inspired by the Spanish Renaissance. It has a rectangular floor plan flanked by two side and one rear square sections, with an elliptical dome covering its central part. The fountains located by the staircases leading to the palace are the work of Carles Buïgas.
The National Palace is devoted to an exhibition of over 5,000 Spanish artworks. Its decoration, 20th century in style, contrasts with the classical architectural style of the building and is attributed to several artists; sculptors Enric Casanoves, Josep Dunyach, Federic Marès and Josep Llimona and painters; Francesc d'Ássís Galí, Josep de Togores, Manuel Humbert, Josep Obiols i Palau, Joan Colom i Augustí and Francesc Labarta.
Between the years 1996 and 2004 the palace was extended by Gae Aulenti, Enric Steegman, Josep Benedito Rovira and Agustí Obiol, with the objective of creating space to accommodate the entire collection.
