Like the tide in the Bay of Authie, the water level in this installation fluctuates with the hours, reflecting the natural rhythms that shape the coastal landscape. This work evokes beaches at low tide, where the relief of the sand is revealed, revealing the traces of the sea’s passage.

Inspired by the lives of the inhabitants of this wild region of Hauts-de-France, who live in harmony with the rhythm of the tides, the installation gives rise to sculpted forms that welcome the movement of the water. Drawn in the patterns of the sand, the stone allows small streams to form, meandering between the undulations. As the tide rises, the reliefs become completely submerged several times a day.

This installation evokes the tide, but also the phenomenon of rising water and the erosion of the dune belt that affects the bay. As with many coastlines, global warming is threatening these preserved landscapes, which are in danger of being submerged in the next few decades.
