Discover the Unique Symbiosis at Coimbra’s Joanina Library

The Joanina Library in Coimbra is home to a unique colony of bats that play a crucial role in preserving its ancient books. These bats, identified as the common pipistrelle, help control the insect population, ensuring the longevity of the library’s priceless collections.
What Makes This Library Stand Out?
Built in the 18th century, the Joanina Library is a stunning example of Baroque architecture, featuring three ornate gilded halls. However, what makes it particularly intriguing are the bats that inhabit its ceilings. These creatures have coexisted with the library for centuries, serving as natural protectors of the books by feeding on potentially harmful insects.
A Natural Pest Control System
The presence of bats in the Joanina Library offers a fascinating glimpse into how nature aids in the preservation of cultural heritage. The bats consume thousands of insects every night, preventing them from damaging the wooden shelves and delicate pages of the books. This natural pest control method is not only effective but also vital for the library’s ongoing preservation efforts.
Daily Preparations to Accommodate the Bats
While the bats are beneficial, their presence comes with the challenge of managing their droppings. Every evening, the library staff thoughtfully cover the leather tables with cloths to protect them from bat droppings, ensuring that both the books and the furniture remain in pristine condition. This daily routine reflects the library’s commitment to preserving its historical treasures while respecting the natural ecosystem within its walls.
Visiting the Joanina Library
Visitors are drawn not only by the library’s architectural splendor and historical significance but also by the chance to witness this harmonious coexistence of humans and wildlife. To experience the library, timed entry tickets are mandatory. This system helps manage visitor flow, allowing guests to enjoy the library’s beauty without overcrowding.
