Biblioteca da Ajuda

The Biblioteca da Ajuda, established in 1880 within Lisbon's National Palace of Ajuda, is one of Portugal's oldest and most prestigious libraries. It serves as the direct custodian of the surviving Royal Library (Livraria Régia), which dates back to the 15th century. The library's history is marked by profound resilience and global impact. After the catastrophic 1755 Lisbon earthquake destroyed the original collection, King Joseph I painstakingly rebuilt the archive. In 1811, during the Napoleonic invasions, the entire library accompanied the Portuguese royal family to Rio de Janeiro, eventually forming the foundational core of the National Library of Brazil. The manuscript collection returned to Portugal in 1821 and was later enriched by secularized religious archives.Today, the library holds over 150,000 volumes spanning from the 12th to the 21st centuries. Its most celebrated treasure is the Cancioneiro da Ajuda, a priceless 13th-century illuminated manuscript featuring medieval Galician-Portuguese courtly love poetry. It also preserves the rare Jesuits in Asia collection, which offers vital historical insights into early European missions in Macau and Japan, alongside an exceptional 3,000-piece collection of 18th- and 19th-century musical scores.Architecturally, the historic library spans five monumental rooms adorned with floor-to-ceiling wooden bookshelves and spectacular trompe-l'œil ceiling frescoes. While tourists can admire portions of its historic architecture, the Reading Room remains a highly functional research hub. It is open Monday through Friday for registered researchers and historians exploring its vast cartographic, iconographic, and manuscript collections.
