The Colegio de Nuestra Señora del Pilar (in English: The School of Our Lady of the Pillar), is a catholic school located in Madrid, Spain. It is often referred to as "El Pilar".
It is a state-funded private day school for pupils from 3 to 18 years of age located in Calle de Castelló, in the Salamanca district.
It was founded in 1907 by the Society of Mary, a Roman Catholic teaching order of priests and religious brothers, who still continue to operate the institution.[1] Founded as a boys' school, it first admitted girls in 1978 and progressively became fully co-educational.[2] El Pilar has educated one Spanish Prime Minister and numerous prominent public figures in the history of Spain.
