The Biblioteca Joanina, renowned for its Baroque architecture, is a gem of the University of Coimbra, established in the early 18th century. It houses a collection of about 70,000 volumes, encompassing works from the 16th to the 18th centuries, reflecting the intellectual pursuits of Europe during that era. The library's design and interior, including its gilded or painted exotic woods and the beautifully painted ceilings, are a testament to the artistic and cultural heritage of Portugal, making it one of the most exquisite libraries in the world.
