It is currently delimited by four prominent buildings: The Bank of Spain, the Palacio de Buenavista, the Palacio de Linares and the Cybele Palace.
Plaza de Cibeles je bil prvotno imenovan "Plaza de Madrid", ki pa ga je leta 1900 Mestni svet poimenoval Plaza de Castelar, ki ga je na koncu nadomestilo njegovo sedanje ime.
