The University of Navarra has had a campus in San Sebastian since 1961, when it inaugurated its School of Engineering. TECNUN currently has two sites. The oldest, located at the university campus in the Ibaeta district, is made up of the laboratory buildings, the professorand representation building, completed in 1989, and a multi-purpose building, erected in 1996. The other headquarters is located in the Miramón Technology Park and includes classrooms and research laboratories in the areas of Electricity, Electronics and Communications.

TECNUN offers 11 Degrees, 1 double Degree, 4 masters and 1 doctoral program.

In addition, the Gipuzkoa Centre for Technical Studies and Research (Ceit), with whose researchers the School of Engineering collaborates for the development of its scientific work, is also located at campus of the University in San Sebastian. In this way, the research necessary in a university institution is complemented with the practical interest of a centre such as CEIT, with a marked character of service to industry.
