 It is difficult to trace a clear line to separate styles as Modernisme, Industrial iron architecture and Eclecticism, as very often architects took some features of several of them for their works.This is the case of Antonio Palacios, co-designer with Joaquín Otamendi of the Palace of Communications of Madrid, inaugurated in 1909.Other works of Palacios include the Círculo de Bellas Artes, the Río de la Plata Bank, the Hospital of Maudes, all of them in Madrid.
