Real Club de la Puerta de Hierro, commonly known as Puerta de Hierro, is a private country club based in Madrid, Spain. It owes its name to the nearby iron memorial arch. Notorious for being associated with the royal families of Europe and the long-established elite, American President Gerald Ford called it "the club of kings and the king of clubs".
