Being a reference in the Argentine Modern Movement, the Colegio Mayor Argentino Nuestra Señora de Luján (CMANSL) is located in the University City of Madrid, Spain. Designed by Horacio Baliero and Carmen Córdova, with the collaboration of Javier Feduchi as the works director and Jesús García Vela as the clerk of works, the building emerged as a result of the competition called by the Ministry of Culture and Education of the Argentine Republic in September 1963. Inaugurated in 1971, it represents an example of modern and organic architecture that, based on a traditional construction system, is capable of addressing the functional and expressive needs of a modern 20th-century building, adapting to the surrounding environment where it stands.
