Palacio de Comunicaciones is located at the Plaza de Cibeles and it is the headquarters of the post office. The landmark, which looks like a cathedral, was built between 1905 and 1917 by Antonio Palacios (1872-1945) and Joaquín Otamendi. Inside the building is the Postal and Telegraphic Museum, which displays the history of the postal system, from the 18th century postal pigeons to the modern communication satellites.
