In Spain, the country conceived as the place of origin of Moorish ornamentation, the interest in this sort of architecture fluctuated from province to province. The mainstream was called Neo-Mudéjar. In Catalonia, Antoni Gaudí's profound interest in Mudéjar heritage governed the design of his early works, such as Casa Vicens or Astorga Palace. In Andalusia, the Neo-Mudéjar style gained belated popularity in connection with the Ibero-American Exposition of 1929 and was epitomized by Plaza de España (Seville) and Gran Teatro Falla in Cádiz. In Madrid, the Neo-Mudéjar was a characteristic style of housing and public buildings at the turn of the century, while the 1920s return of interest to the style resulted in such buildings as Las Ventas bullring and Diario ABC office. A Spanish nobleman built the Palazzo Sammezzano, one of Europe's largest and most elaborate Moorish Revival structures, in Tuscany between 1853 and 1889.
