Cathedral of Santiago de Compostella or the Giralda of Seville. Interior decoration The architectural project not only included architectural decoration such as columns, pediments and moldings but also considered such interior decoration as murals and sculptures. The ornamentation of the interior spaces depended on the organizational committee who resulted in giving the amount of 1,200,000 pesetas towards its realization. Responsible for the project management was Louis Plenduira, curator of the Fine Arts Exhibition. The work commenced in winter of 1928, leaving the artists three months to carry out their pieces. The style of the art work produced belongs to that of which prevailed in Catalonia at the time namely the noucentisme style, which is found especially in the decoration of the main dome and the domes under the Throne Room, the Great Hall and the Tea Room. The neo-Renaissance architecture contrasts with its 20th-century decoration by 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. The Great Hall Beyond the lobby is the Great Hall (), or Oval Room (). Due to its large dimensions, it was conceived as a space for the hosting of great events; from the official ceremony to the inauguration of the Exhibition, as well as concerts, balls, galas and conferences. The hall is 2,300 m2 and has standing room for 1,300 people. The Oval Room hosted the opening ceremony of the Exhibition, presided by Alfonso XIII and Queen Victoria Eugenie. The Great Hall is covered by an oval shaped coffered vault, with large columns dominating the decoration. The column's shafts are adorned with a Renaissance grotesque decoration. The decoration is simple, consisting of ornamental borders and basic vegetation motifs, which line both the arches and the coves of the vault. Another design element of the Salon is the fifty-six small heraldic shields which occupy the space between the arches and represent the fifty Spanish provinces which existed in 1929. The six remaining shields depict musical instruments and are located in the part of the Salon where the organ is found. For the Universal Exhibition of 1888 in Barcelona two electric organs were installed in the Salon of the Queen of Regent of the Palace of the Fine Arts (Palau de les Belles Arts); this initiative being faithful to the tradition undertaken in other
