On International Day for Monuments and Sites, we planned a guided tour to the Documentation and Information Centre, to the Storage, Conservation and Restoration Department, and to the Benfica Museum - Cosme Damião. The professionals of Sport Lisboa e Benfica's Cultural Heritage Department share their daily lives and, under the theme "Heritage Changes", open the discussion on the particularities and evolution of sporting heritage. What challenges and working practices follow this transformation? Come and find out!
