The Joan Miró Foundation opened to the public on June 10th, 1975. It had its origins in Miró's first large exhibition in Barcelona in 1968, at the Old Hospital de la Santa Creu (Holy Cross).
The Foundation holds a large collection of drawings, correspondence, books, exhibition catalogues, journals, and other documents donated by Joan Miró. These archives include from the first published pieces in the beginning of the artist's career, to the most recent publications.
The Foundation building was designed by Josep Lluís Sert, architect, co-founder of the Group of Architects and Technicians for the Progress of Contemporary Architecture or GATCPAC (for its acronym is Spanish), and a close friend of Joan Miró. It was built on land ceded by the City Council in the Parc de Montjuïc. Towards the end of the 1960s, Sert and Miró began working on the idea of a "Miró Museum" on the above mentioned site.
In 1988, it was enlarged to increase the exhibition space, provide room for new services and relocate the offices. The extension was designed by Jaume Freixa, a friend and pupil of Sert.
The collection The Foundation's collection currently comprises over 14.000 pieces including paintings, sculptures, textiles, ceramics, practically the entire graphic work and some 10.000 drawings. The great bulk of this collection was donated to the Foundation by Joan Miró himself and his wife, and Joan Prats, his close friend and the driving force behind the idea of setting up the Foundation. The collection has increased with subsequent donations.
The Miró family made also a permanent loan to the Foundation of the artist's private library.
