At the beginning of 1972, as part of a competition organized by the Ministry of Education, Alejandro de la Sota would begin a rather short, but certainly intense, process that would lead him to build the classrooms and seminars of the University of Seville, which today house facilities of the Faculty of Mathematics.

The work was implanted in an incipient university campus that marks the limit between the Sur and Bellavista-La Palmera districts of the city of Seville, in an area that at that time was outside the urban nucleus, and that concentrated uses rather associated with manufacturing and port activities.

With more than thirty years of professional practice under his belt, at that time De la Sota was already an architect who had known how to gain recognition throughout Spain through works such as the town of Esquivel (Seville, 1952-1963) for the National Institute of Colonization, the building for the Civil Government of Tarragona (1954-1957) or the well-known Gymnasium of the Colegio Maravillas (Madrid, 1960-1962). However, it was precisely this, perhaps one of his most neglected works in the historiography on the architect, that earned De la Sota recognition with the 1974 National Architecture Prize.
Alejandro de la Sota won the competition for the construction of the classrooms and seminars of the University of Seville in 1972, in such convulsive conditions that led him to start the work with only the basic project and to define the executive aspects as construction was progressing. This demand from the promoter meant that De la Sota was forced to put aside his most exploratory face in pursuit of the urgency of the work, although of course, without missing even the smallest detail in its material resolution and constructive.

Located in a purely academic enclave, the Faculty of Mathematics is surrounded by its peers (mostly non-existent at the time) of Architecture, Engineering and Physics, among others, open to the rest of the Reina Mercedes University Campus in the east, and hidden in front of the vast constructions of the Sevillian port that prevent resting the gaze on the Guadalquivir.

From there emerged a typological approach that adapts to all these contextual and temporal constraints, which became a project that boasts of late rationalism that oscillates between revisionist and the purest modern tradition, and that knows how to respond to the demands of its use in the most functional and efficient way possible for the time.

Faced with this, De la Sota's strategy consisted of drawing a central patio plan that intentionally turns its back on its surroundings, in favour of interior green spaces that are not practicable in their traditional way, but rather act as excuses for the incorporation of direct natural light to the building, and that are only crossed by concrete and steel walkways that connect the classrooms and seminars with the cafeteria and the assembly hall.

Materially, the resolution is very specific in terms of varieties: brick, glass and steel. De la Sota, however, knows how to exploit his qualities as only some of his national and international peers would do in the most studied works of architecture of that century. Faced with the purity of the rationalist interior facades, the steelwork, for example, is sublime in its plastic resolution, almost ornamental, with its reddish browns (today light blue), and pairs perfectly with industrial tectonics and ostentation by moments until overwhelming of that structure in sight that runs through every corner of the building.

During the next 21, 22 and 23 October, as part of the first edition of the Open House Seville International Architecture Festival, the Faculty of Mathematics will open its doors so that anyone interested can visit this magnificent example of rational Spanish architecture in the second half of the 20th century.

Alejandro de la Sota (Pontevedra, 1913; Madrid 1996) is one of the greatest masters of the Spanish Architecture of the 20th Century. He was a professor at the School of Architecture of Madrid (ETSAM),  serving its trail as a reference for several generations of Spanish architects.

During the thirties, he moved from his home town Pontevedra to Madrid where he started his studies in the Faculty of Mathematics, which was a necessary condition to enter the School of Architecture. Once he got his degree in Architecture in 1941, he spent the first years of his professional life working for the National Institute of Colonization; a stage that ended up with the construction of the village of Esquivel (Sevilla, 1952-1963) and Arvesú House(Madrid, 1953-1955, demolished). Since then, he participated in different competitions, following the same idea as he did in his previous work, the Civil Government of Tarragona (1957-1964). This building has been considered by many people his first masterpiece. During this prolific period, he did several projects of modern industrial architecture, such as the Clesa Dairy Plant (Madrid, 1958-1961) and CENIM premises in the Campus of the University(Madrid, 1963-1965) and he also built his most recognized and admired work, the Gymnasium of Maravillas School (Madrid, 1960-1962); which is considered by the British critic William Curtis, the most significant work of Contemporary Spanish Architecture.

In 1960 he obtained a job as a Government officer at the Post Office, and throughout this decade, he researched the possibilities that new materials provide and developed several projects based on a constructive approach consisting of the use of prefabricated concrete panels for walls and floors. This idea is shown in Varela’s House in Villalba (Madrid, 1964-1968).

In 1971 he left the university education as a professor, coming back to his public service position at the Post Office. During these years he built César Carlos Residence Hall on the Campus of the University (Madrid, 1968-1971), the building for class and lecture rooms of the University of Sevilla (1972-1973) and Guzmán’s House in Santo Domingo‘s urbanization (Madrid, 1972-1974), in which he tried out issues to be applied afterwards in Domínguez’s House in A Caeira (Pontevedra, 1973-1978).  The Computer Center for the PO Box in La Vaguada (Madrid, 1972-1977) and years later, the Post and Telecommunications Building in León (1981-1984) belong to a stage where he was completely involved in light prefabricated techniques.
