Located in the district of Les Corts, the complex known as Casa Provincial de Maternitat is located on the block of houses bounded by Travessera de Les Corts and Carrer de la Maternitat, Doctor Salvador Cardenal and Mejía Lequerica Streets. The main access to the complex is from Travessera de Les Corts. The complex is made up of a large group of pavilions built in different phases and distributed within a large, enclosed area. The original core of buildings, located at the southern end of the plot, is composed of five pavilions arranged around a large rectangular courtyard. These buildings have a height development consisting of a semi-basement, two floors and attics. They show a clear compositional unity and general arrangement, with a unique treatment of façades and a game of textures achieved by mixing exposed brick with stone walls. While the plinths of the buildings are made of regular stone blocks placed at break-joints, on the other levels the work is of common masonry. These textures are separated at the level of the slabs by rows of work with a slight overhang, where polychrome ceramic friezes stand out along the entire perimeter of the building. The crowning consists of a barbican that goes around the entire perimeter simulating a defensive enclosure. The constructions started during the period of the Mancomunitat, meaning that the Pink and Blue Pavilions were designed by Josep Goday i Casals in a style closer to Noucentisme. The Pink Pavilion recovers the characteristic motifs of the Catalan Baroque, with the inclusion of sgraffitos (geometrising borders and baskets) and terracottas. The putti and the shield of the main door solved in the form of a shell were done by Canyellas, and the crowning is based on balusters and vases. The Blue Pavilion has earth-coloured sgraffito coverings on its façades; it received its name from the name of the glazed ceramic dome that crowns the central body. The Pavilion of Helios represents a turning point, bringing to the whole a building within the rationalist current of the GATCPAC. Founded in 1853, the Casa Provincial de Maternitat i Expòsits was originally located in the Casa de Misericordia (Carrer Montalegre), in the old town. With the hygienist currents of the moment, the City Council decided to improve the conditions of the institution by promoting the construction of buildings suitable for its sanitary function. For this purpose, in 1878 they acquired the Can Cavaller country house, in Les Corts. The architect of the City Council, Camil Oliveras i Gensana, together with the architects General Guitart i Lostaló and Josep Bru, designed the Lactation Pavilion, the two Infectious Pavilions and the Laundry between 1885 and 1889. In 1920, the transfer of powers of the charity services between the City Council and the Mancomunitat took place. The construction plans, which until then had been carried out by the institution, basically concerned the orphanage section, so Josep Bori drew up an ambitious project for the maternity section that should be developed on the land located to the north of the site. In 1915, the construction of the Pink Pavilion began, started by Rubí i Bellver and completed in 1924 by Josep Goday, intended to accommodate secret pregnancies or unmarried mothers. Between 1928 and 1942, the same architect built the Blue Pavilion, destined for the Maternity Clinic. Between 1933 and 1936, Goday built the Helios Pavilion, intended for children with tuberculosis, following the structural and aesthetic guidelines of GATCPAC's rationalism. After the Spanish Civil War, the institution lost the progressive and renewing attitude of the previous dynamic period and returned to being governed by the traditional concept of Christian charity, abandoning the concept of modern public service. In this context, the economy of the institution was very precarious and the construction of a new pavilion for children aged 2 to 3 could only be carried out thanks to the legacy of two million pesetas by Francesc Cambó i Batlle. The architect Manuel Baldrich i Tibau oversaw its construction between 1953 and 1957. With the start of work on the Llars Mundet in 1954 and seeing that the buildings of the Maternity Hospital were no longer suitable for the social needs of the moment, the Council began to reconsider the uses of the site. Finally, in 1985, the Action and Planning Plan for the Maternity Home was approved, drawn up by the architects Josep Lluís Canosa and Carles Ferrater. This document laid the foundations for converting the existing buildings into public buildings intended for equipment and services, concentrating all hospital services in the Blue Pavilion and turning the outdoor spaces into a park. Currently, the Lactation pavilion is occupied by the Consortium of Resources for the Integration of Diversity (CRID), the Tourism Delegation, the Area of Economic Promotion and Employment and the Tax Management Organization (ORGT); the Pavelló de Desmamats is the seat of the Ministry of Health of the Generalitat of Catalonia; in the old infectious disease pavilions there is the Directorate of Urban Planning and Housing Services, the Institute of Urban Management and Local Activities (IGUAL) and the Institute of Local Housing (INHAL); the Historical Archive of the Barcelona City Council was installed in the Laundry; the headquarters of the Distance Education University (UNED) was installed in the Pavilion of the Kitchens; the Pink Pavilion would cease to fulfill its function in 1974 and, fifteen years later, would host the offices of COOB'92. The Blue Pavilion has hosted, since 1993, the Hospital Clínic Health Consortium; the Cambó Pavilion has been home to the Jordi Rubió i Balaguer University School of Library Science since 1991; and since 1989, the Prat de la Riba Pavilion has been home to Les Corts Secondary School.
