ARCHITECTURAL STRUCTURE

56 metres above the watercourse and more than 50 metres long, it has a unique arched structure built entirely using masonry and designed with a double passageway. The open-air top level was intended for the passage of water, paved with large hewn stone slabs covered with a specific type of mortar to allow water to run over it. The lower level, covered but ventilated with openings to allow natural light to enter, meant pedestrians could cross and it was accessible via two entrances. The project was part of an aqueduct whose water source was in the hamlet of Chevril (975 metres above sea level) and ended in Aymavilles, where the water was actually used in the working of the high-quality Bardiglio marble which, in the 1st century CE, was used to fill the city of Augusta Prætoria with monuments. Without a doubt this aqueduct-bridge is one of best examples of the synthesis between architecture and engineering in the Roman world in Northern Italy.
