Noria of Alcantarilla

Noria of Alcantarilla is a 15th-century waterwheel still operating in the town of Alcantarilla, in the Murcia region of southeastern Spain. It lifts water from the Acequia Mayor, the main irrigation channel of the Huerta Murciana, and has been feeding fields set above the channel's water level for more than five centuries.

Where does this waterwheel come from?

Construction was requested by the Diocese of Cartagena, which petitioned the Murcia city council in 1451 for permission to build it. The wheel was completed in 1457. The aqueduct that accompanies it was built in two distinct phases — one from the 15th century and another from the 16th — and has been repaired and modified repeatedly since, while keeping its original layout intact. The word "noria" itself comes from the Arabic an-na'ura, meaning a waterwheel driven by the current.

The wheel visible today is not the 15th-century original. The current structure was installed in 1956 by the Sociedad Metalúrgica Naval y Terrestre of Alicante. It replaced the earlier wooden wheels, which needed constant rebuilding because of their permanent contact with water.

What will you see there?

The wheel measures 11 metres in diameter, 1.90 metres in width, and rises 8 metres above the water flowing through the Acequia Mayor. It is built as a double structure — two rims, each fitted with 36 cangilones (scoops), for 72 scoops in total. Each scoop fills with water at the base of the wheel and empties it out at the top of the turn.

An integral part of the site is the aqueduct, originally made up of 25 arches, some of which no longer survive. Water raised by the wheel flows into it, then continues through a second stretch known as the Cequeta aqueduct toward a network of smaller channels, including the Acequia de la Alquibla (also known as Barreras), from where it spreads by gravity across the fields of the Huerta Murciana that sit higher than the main channel.

The mechanism still works exactly as it did in the Middle Ages: the current turns the wheel, the scoops fill, and at the highest point of the rotation they tip their water into the feeder channel. It is a rare case of medieval irrigation engineering still doing its original job, rather than standing as a museum piece.

How do you get to the Noria of Alcantarilla?

Alcantarilla sits a few kilometres southwest of central Murcia and is well connected to the city by local and regional roads. The wheel itself stands within the town, right along the course of the Acequia Mayor, in an easily reachable spot — no drive out into open countryside or long walk is needed.

When is the best time to visit?

The wheel runs year-round, since it is driven by the constant flow of the channel rather than the season. Murcia has hot summers, so spring and autumn make for a more comfortable time to walk around the site and take in the aqueduct without rushing.

Frequently asked questions

Is the wheel still working, or is it just a display piece? It genuinely lifts water from the Acequia Mayor and uses it to irrigate fields above the channel's level — this is working infrastructure, not a static replica.

Is the current wheel the original 15th-century one? No. The first wheels were made of wood and needed frequent rebuilding. The present metal wheel was installed in 1956.

How many scoops does the wheel have? 72 scoops (cangilones), 36 on each of the wheel's two rims.

What is the aqueduct standing next to the wheel? It is an aqueduct built in two phases, in the 15th and 16th centuries, originally consisting of 25 arches through which water raised by the wheel was carried onward into the irrigation channel network.
