The observatory aims to educate the public about the importance of preserving these fragile environments. Occupying 700 square meters within the Tower and Logis Perrière, the observatory presents interactive exhibits that explore the biology, ecology, ethnology, archaeology, and limnology of the French Alps' lakes. These exhibits showcase the complexity and fragility of these coveted environments, with a primary focus on Lake Annecy, Lake Bourget, and Lake Geneva. Visitors can explore sub-aquatic archeology, flora and fauna, fishing practices, and the impact of tourism on these delicate ecosystems. ORLA uses aquariums, models, films, and reenactments to illustrate the importance of preserving the rich biodiversity of alpine lakes. Exhibits showcase the species that inhabit these lakes, including invertebrates, fish, and birds. The ethnology section explores how humans have historically interacted with the lakes through fishing, highlighting the significant decline in professional fishermen over the past century.
