At first sight, the Arrosadía Campus shows the predominance of the straight line in buildings and perspectives. The most impressive building is the library, it has 9.000 square metres and is placed longitudinally in the centre of the campus. From the exterior the library seems a polygonal solid building but the interior is transformed into a large space crowned with a vault through which the light softly shines through inviting to concentration and learning.

The library is the centre of learning, deposit of science. It collects and distributes the knowledge of the different university disciplines. For this reason the department buildings are placed at each side of the library. Like this, it symbolises a reality. Everybody is supplied by the library and simultaneously everyone supplies the library with her or his teaching and research activity.

At the back of the library, stands the 'Aulario', a rectangular building occupying the northern flank of the campus. Its the closest to the city centre and has the largest parking lot to give direct access to teachers and students to the 124 classrooms in the building.

Along the sides of the library you can enjoy a long walk. The architect, Sáenz de Oiza, reproduced the dimensions of the Sarate Paseo - in the city centre - on the Arrosadía campus. At the end of this open space stands the Rectory building, once again a glassed topped polygonal building that intends to collect the surrounding light and at the same time, radiate the light from inside.

All the buildings designed by Sáenz de Oiza converge towards a single point detached from the University. Every line is directed to the Higa de Monreal, a mountain nearby Pamplona, a natural pyramid that defines the area.

There are other buildings and centres close to the complex site organised by Sáenz de Oiza, such as the Institute of Agrobiotechnology and Natural Resources, the Sario building where the old Industrial Engineering School used to be and which holds other university services, for example Room '0' that has a capacity for 600 people, used for scientific meetings and conferences.

The campus of the Public University of Navarre is designed by the creative and controversial architect, at theoretical and practice levels, Javier Sáenz de Oiza. Originally from Navarre, concretely from Cáseda, he has universal works: the Monastery of Aránzazu, the BBV central office in Madrid, the Modern Atlantic Art Centre in Las Palmas or the Palace of Festivals in Santander.

In Pamplona, Sáenz de Oiza has left the trace of his creative force, building the University of the XX century, serviceable and not subject to the typicality. On a surface of over a quarter of a million square metres, he framed a system of buildings that create a favourable atmosphere for working, learning and the interrelation between the university collectivities.
