On 18 November 1996, the Casa do Patín opened its doors to the public as a University Library. On the occasion of our 20th anniversary, we set up an exhibition where you could see a model of the library, a bibliographic selection about the Casa do Patín and the campus and a photographic exhibition of before and after the restoration. We also put a book of signatures and the graphic designer Carlos Sardiña (www.telodibujamos.com) created the poster to commemorate the anniversary.
