Royal Site of San Lorenzo de El Escorial

7 Libraries Set Inside UNESCO World Heritage Sites | Condé Nast Traveler

"Part of the UNESCO-listed Royal Site of San Lorenzo de El Escorial, this late-16th-century library founded under King Philip II served as a repository for humanist learning. A long barrel-vaulted hall completed by architect Juan de Herrera embodies the sober classical style of the larger complex, while a collection of over 40,000 volumes includes Greek and Arabic manuscripts, early cartographic works, and rare scientific treatises gathered from across the Iberian world. Shelving follows a forward-thinking “wall system,” storing books upright along the perimeter to improve ventilation, and frescoes by Pellegrino Tibaldi depict the liberal arts and the four faculties of medieval knowledge. Access to the hall is controlled, with only a portion of manuscripts shown in rotating cases." - Navya Verma
