The Telefónica Building is a skyscraper designed by Ignacio de Cárdenas, who conceived it after a previous study of Lewis S. Weeks in Manhattan. Even though the building is of American inspiration, Cárdenas touch can be felt in its churrigueresque exterior ornamentation, a nod to Madrid Baroque architecture. Its construction started in 1926 and finished in 1929, despite opening its doors in 1930. The workforce was composed of more than 1000 workers and the final cost added up to 32 million pesetas. It became one of the first skyscrapers in Europe. It held the Madrid height record by surpassing the Palacio de la Prensa, which it maintained until it was overtaken in 1953 by the Edificio España.
