The architecture of Spain of the 1920s and 1930s remains a little studied aspect of the emergence of the modern movement. In 1926 –1931 the architects Carlos Arniches and Martín Domínguez, both prominent members of the so called ›Generación del 25‹, constructed a country estate near Córdoba for the Marqués de Murrieta. The remains of the now lost villa and garden have recently been investigated by the German Archaeological Institute, as part of a comprehensive study of the 10th century Islamic palace on which the estate had been built. The singular design of the building attests to the search for a new style of architecture based on the ›honest‹ rural architecture of Andalusia, as called for by Fernando García Mercadal and others. The design of a promenade architecturale moreover hints at the innovative potential of the architects and their contribution to the modern movement in Spain.
