Real Club de la Puerta de Hierro

Real Club de la Puerta de Hierro is a private country club located in the Fuencarral-El Pardo district of northwest Madrid, Spain, taking its name from the nearby baroque triumphal arch built by Ferdinand VI in 1753. The club was founded in 1895 as a polo club by a group of prominent noblemen led by the 16th Duke of Alba, with the active support of King Alfonso XIII. Golf was introduced shortly afterwards, initially at the Hipódromo de la Castellana, and in 1912 the club relocated to its present site on land provided by King Alfonso XIII at a nominal annual rent, adding the prefix Real and adopting the name of the monument at the entrance to the estate.

The first 18-hole course, known as the Arriba or upper course, was designed by Harry Colt and opened in 1914. Colt noted at the time that it would be difficult to find a site with greater natural aptitude for outstanding greens. Tom Simpson was subsequently called in to remodel the layout in 1924, and Colt returned for further modifications in 1931. Simpson lived at the club between 1946 and 1949, working on additional holes, and further changes were made by John Harris in the 1960s. The Arriba course has received its most recent revisions from Robert Trent Jones Jr and Kyle Phillips. The Abajo or lower course, which is considered the more competitive championship layout, was substantially redesigned by Robert Trent Jones Jr and Kyle Phillips in 1998, though several original Colt holes from 1914 are retained, including the first, third, and fourth. A standalone nine-hole course called Buena Vista, designed by Kyle Phillips, opened in 2018. The Arriba course measures around 6,375 metres from the back tees to a par of 72, and the Abajo is a par 72 of approximately 6,052 metres, both routed through a mature holm oak forest with views of the Sierra de Guadarrama mountains.

The club hosted the Madrid Open on the European Tour from 1972 to 1993, with winners including Seve Ballesteros, Ian Woosnam, Bernhard Langer, and Sandy Lyle. It is strictly private and accessible only to members and their guests. American President Gerald Ford is reported to have described it as "the club of kings and the king of clubs." Both courses rank among the leading layouts in Spain and are consistently placed among the top courses on the Iberian Peninsula.
