Description

Loop starting from the Promenade Museum passing by the Plâtrières, the Dalle aux ammonites and returning by the gentle route. Please note: The visit to the promenade museum is subject to a fee.With more than 1500 ammonite and nautilus fossils grouped together over an area of ​​320 m², the ammonite slab is undoubtedly the emblematic site of the Geopark of Haute Provence.

To understand the emergence of this seabed, we must return to the “Lias” (Lower Jurassic). At this time, our region is literally underwater, the marine space is deepening and expanding through ocean expansion. The sea is then teeming with life and marine animals are abundant.
The ammonite slab, as well as nearby sites, bear witness to the early stages of the development of the Alpine chain and what life was like in this ocean before the rise of the Alps. They allow us to understand the environment and the conditions that reigned at the time of these seabeds.
Today we can observe more than 1500 ammonites of all sizes on this “ammonite slab”, the largest are up to 70 cm in diameter!
The very good preservation of the shells once again allows us to bear witness to the marine activity of the time.
Their scientific name, coroniceras multicostatum, allows us to date the slab to around 200 million years old.

Musée Promenade

The Musée-Promenade stands as the interpretive centre of the UNESCO Geopark of Haute-Provence. Visitors wander through a sprawling shaded park where pathways and streams intertwine, and where cascades and contemporary artworks come together to create an enchanting setting."Picnic facilities and open toilets are available. Embark on a journey to encounter butterflies, wander leisurely or learn about the geological history of the region and the global network of UNESCO Geoparks. Internationally renowned artists such as Andy Glodsworthy, Joan Fontcuberta, Sylvie Bussières or Agathe Larpent got their inspiration from here. An area for wandering and creation, overlooking Digne from its rock, it immerses the visitor in a quiet atmosphere leading him to the heart of the Earth’s memory… In the exhibition rooms, the last 300 million years of Earth’s history unfold before our eyes. In ancient times, the alpine ocean was covering the region. Tropical marine aquariums illustrate this memory, juxtaposing colourful living species with stone fossils, of which Ammonites and Ichthyosaurs are the kings. A film tells the history and the evolution of the landscapes of the region as well as the great transformations that the Earth has undergone. It enables each person to grasp the extraordinary richness of this territory. Japanese garden To discover within the Musée Promenade : the Kamaïshi Japanese garden. Of Japanese inspiration,this garden was conceived as a tribute to the twinning of Digne and Kamaïshi around the theme of “Man and the Seasons”. The various stages of a person’s life are represented through progressive blooms along the pathway. Each entrance is marked by a Japanese-style gate, inviting visitors to enter the garden. A bridge, a pond, paths, benches, carefully chosen vegetation, lanterns and pagodas coexist harmoniously in this timeless space accessible to all (with wheelchair access). The Butterfly Trail Between waterfalls and terraces specially designed to host the favourite - or exclusive - plants of butterflies and their caterpillars, in this particular environment on the edge of mediterranean and alpine climate, more than 139 species of butterflies live freely and can be observed from spring to autumn.
