Museum of the University of Coimbra), and an academic museum (Academic Museum of the University of Coimbra). The university has five main campuses or other sites: Pólo I (the monumental ancient university core centre, with the main library and administration services, as well as faculties of law, medicine, letters, psychology, and natural sciences – active since the early university times before the 16th century, with major expansions in the 18th century and from the 1940s to the 1960s, during Estado Novo) Pólo II (engineering, sciences & technology – built during the 1990s and 2000s) Pólo III (medicine, pharmacy & the university hospital – built in the 1980s with major expansions in the 2000s) Faculdade de Economia (economics, social sciences – founded in the 1970s) Faculdade de Ciências do Desporto e Educação Física (sports sciences – founded in the late 1990s in the university sports complex) Students Students are represented by the students' union Associação Académica de Coimbra (AAC). Formed on 3 November 1887, it is the oldest university students' union in Portugal, with a long history of struggle against unpopular state policies, forming notable politicians and intellectuals along the way. It also harbours a very dynamic associative life, with its numerous sports and cultural sections, as well as a number of other autonomous organizations. It is an important structure of extracurricular formation of the University of Coimbra's students and a major institution of the city itself. The AAC develops activities such as theatre, cinema, radio and television broadcast, music, choral singing, journalism or philately, as well as rowing, athletics and many other sports. Every student, and occasionally some non-students, are entitled to belong to these sections. Culture, sports and traditions The university's academic traditions and institutions color the life of the city. The old "Republics" (autonomous students' residences) remain, as well as some traditional festivities, most notably the "Queima das Fitas" (a celebration of graduation's end, symbolized by the burning of the ribbons with the colors of each of the eight faculties), the "Festa das Latas" (a homecoming), the frequent use of traditional attire, the "Fado de Coimbra" (Coimbra's fado, now sung in organized shows rather than the traditional street serenades), and the academic ceremonies (namely the conferring of doctorate degrees). The official colors of the Faculties of the University of Coimbra are: Faculty of Law: Red Faculty of Medicine: Yellow Faculty of Humanities: Dark Blue Faculty of Sciences &
