The project '20th century architecture in Spain, Gibraltar and the French regions of Aquitaine, Auvergne, Languedoc-Roussillon, Limousin, Midi-Pyrénées and Poitou-Charentes'began thanks to the initiative of four institutions: Iberian DOCOMOMO Foundation, Arc en rêve centre d'architecture, Government of Gibraltar Town Planning Section and the Mies van der Rohe Foundation, which were joined by participating partners, the Arquia Foundation and the Ordem dos Arquitectos Portugal.
The overall purpose of the project was to create an inventory with the architectural heritage of the 20th century in Spain, Gibraltar and the French regions included in the 'Sudoe', a term used by the European Union to designate the geographical area encompassed by the Iberian Peninsula and said regions.
The project was accepted in the second call for proposals in July 2004, Community Initiative INTERREG 3rd B Southwest (SUDOE) of the European Regional Development Fund (ERDF) of the European Commission. Thanks to the grant of the fund and joint financing by the Mies van der Rohe Foundation, the DOCOMOMO Foundation and the Arquia Foundation the project was carried out, resulting in a database that could be searched from the internet, the production of a CD-ROM and an exhibition.
The Arquia Foundation makes the information from the 'Arch 20th SUDOE Spain' database available to its users.
