An interactive history-and-ecology project follows the vanished Bièvre river from Cachan into Paris.

Landing page captured for the 2026-09-12 issue.

Field notes

Invisible Bièvre uses a walking route between Cachan and Paris to connect a disappeared river with Roman infrastructure, former bridges, gardens, street art, and local museums. Its proposed interaction is proximity-based: the web app is intended to make the river and its stories grow stronger as visitors approach hidden traces. The project credits AR/VR developers, writing, 3D modeling, and art direction, and says its first story will launch at the Arcueil-Cachan Roman Aqueduct.
