The Bilbao campus was declared a site of historical interest in 2002. Several architecturally valuable buildings are found on the campus. The most outstanding is known as the Main Building (Edificio Central) and has a classic style. Its most distinctive features are its central staircase, the Library (currently the Salón de Grados), the Gothic Chapel and the Main Hall.
The Comercial Building is known for its neoclassic façade. The so called “Glass Building” or “Centenary Building” was built in the 80s. The last emblematic building on the Bilbao campus, the ESIDE Building, is more modern in style and was designed by the César Sans Gironella.
