The Joanina Library (Biblioteca Joanina) is the Baroque library of the University of Coimbra, built in the 18th century during the reign of the Portuguese King João V (and named after him). It is located in upper Coimbra, the university historic centre, near the university tower, and is part of University of Coimbra General Library.
Over the entrance door, the library exhibits the national coat of arms. Inside, there are three great rooms divided by decorated arches, bearing the same style as the portal and entirely executed by Portuguese artists. The walls are covered by two storied shelves, in gilded or painted exotic woods; the painted ceilings, by the Lisbon artists Simões Ribeiro and Vicente Nunes, blend harmoniously with the rest of the decoration. The library contains about 250 thousand volumes, namely works of medicine, geography, history, humanistic studies, science, civil and canon law, philosophy and theology. It is a National Monument and has a priceless historical value being one of the main tourist attractions among the older monuments belonging to the university. source: wikipedia
