The Natural Sciences Museum of Barcelona is opening a part of its facilities that has been previously inaccessible. Located at Parc del Fòrum, the museum has recently undergone a renovation, leading to the relocation of some scientific collections. This new phase sees the museum merging public exhibitions with areas dedicated to scientific research and heritage management. Visitors will be treated to guided tours led by experts who manage and care for natural heritage. During these tours, guests can explore normally off-limits areas including reserves, warehouses, and laboratories, gaining insight into the collection preservation processes. This is a unique opportunity to understand how the museum conserves and restores its extensive natural collections, and to appreciate the importance of scientific research within the museum's framework.
