Noria avec son mécanisme

Noria avec son mécanisme is a historic water wheel standing beside an irrigation canal in the village of Cazilhac, in the Hérault department of southern France's Occitanie region. It is one of the few surviving examples of a once-common water-lifting system that irrigated fields and gardens for well over a century.

What is this noria and what was it used for?

A noria is a water wheel that harnesses the current of flowing water to lift that same water to a higher level, with no pump, motor or outside power source involved. The wheel in Cazilhac measures roughly 5.5 metres across and carries sixteen buckets spaced evenly around its rim. Each bucket fills at canal level as the wheel turns, then tips and empties into a collecting channel at the top of its arc, sending the water onward through a network of ditches that fed the surrounding land.

When and why was it built?

The wheel was most likely raised around 1880, in the years following the purchase of the surrounding land by its owners in 1871-1872. The project belonged to a broader wave of agricultural modernisation along the Plaine irrigation canal during the second half of the 19th century, as landowners along the waterway installed similar wheels to make better use of the available water and irrigate plots sitting well above the canal's own level.

Is this the only wheel of its kind in Cazilhac?

No - it forms part of a longer local tradition known as "meuses". This network of water wheels in Cazilhac dates back to the late 18th century and was built to raise water from the canal into a holding basin, from which it could be distributed to fields far above the canal itself. Six of these meuses are still in working order today: five have been recently restored, and one - the very wheel described here - has been granted heritage protection. That combination makes Cazilhac an unusually complete place to see a whole set of historic hydraulic devices still working in their original rural setting.

What protected status does the noria hold?

The wheel and its entire mechanism were listed as a monument historique by a decree dated 13 November 1980. The protection covers the noria together with its mechanism, standing on the Plaine irrigation canal. The site remains private property, which is worth knowing before a visit - it can be viewed from outside, but it is not set up as a museum open to the public.

What else is worth seeing nearby?

Cazilhac lies close to Ganges and the Hérault river valley, an area known for scenic gorges, caves and walking trails. A visit to the noria pairs well with a short stop along the canal to watch the wheel's slow but constant turning - a rare sight, given that it has been running on nothing but the force of flowing water for close to a century and a half.

Frequently Asked Questions

Where exactly is the noria located? It stands on the Plaine irrigation canal in Cazilhac, in the Hérault department, Occitanie region.

How does the wheel's mechanism work? The wheel, about 5.5 metres in diameter, is turned by the current of the canal. Sixteen buckets fill at canal level and empty into a collecting channel at the top of the turn, feeding the local irrigation network.

When was this noria built? Most likely around 1880, in the years after its owners purchased the land in 1871-1872.

Is the noria legally protected? Yes - the wheel and its mechanism were listed as a monument historique by a decree of 13 November 1980.
