laziosotterraneo

A technical and editorial archive dedicated to the underground works of Lazio: emissary tunnels, aqueducts, rock-cut passages, hypogeal spaces, ancient hydraulic structures and archaeological evidence that is often barely visible in the modern landscape.

The project brings together articles, graphic reconstructions, maps, survey notes and interpretive sheets, with attention to both historical understanding and technical construction aspects.
