@emilyexpedition: In Portugal, some of the country’s most historic libraries are protected by unlikely guardians: bats. At libraries like the Biblioteca Joanina in Coimbra, colonies of bats have lived inside the buildings for centuries. Each night, they emerge to hunt insects that could damage priceless books, providing a natural form of pest control. This unique relationship between wildlife and historic preservation highlights the unexpected ways nature and cultural heritage intersect. #Portugal #CulturalHeritage #HistoricLibraries #Conservation #Bats
