Conjunto hidráulico Las Calabazas

Las Calabazas hydraulic ensemble sits on the right bank of the Rambla de las Calabazas (also called the Rambla del Pollo) in Huércal de Almería, in the province of Almería. It works today as a small open-air museum, laying out more than a century of changing technology for pulling irrigation water out of the ground for the surrounding table-grape vineyards — starting with an animal-powered wheel, moving on to a mountain canal, and ending with the first electric pumps.

What is actually on site?

The ensemble is made up of two separate water-extraction installations roughly 170 metres apart, linked underground by an arched drainage gallery close to 100 metres long.

The eastern installation is the older of the two: a blood-powered noria (a waterwheel turned by draft animals) built on a stone masonry drum about 10 metres across, with window openings and a door facing east. Next to it stands a circular reservoir around 18 metres in diameter, reinforced with concrete, plus a platform raised on concrete pillars and a later chamber that housed the electric motor which eventually took over from animal power.

The northern installation, 170 metres away, centres on a former noria yard that has since been sealed up, a well ringed by a conical stone kerb with brick arched openings, and a second reservoir about 19 metres across. Here too, water was later pumped by an electric motor rather than drawn by animals. A network of distribution channels and a rectangular collection tank tie the whole system together.

How did the water technology evolve here?

The first animal-driven norias went up in the mid-19th century, when growing exports of table grapes demanded more water than older methods could supply. In the 1880s the Canal de San Indalecio reached Huércal de Almería, bringing water down from the mountains and substantially boosting the amount available for irrigation. By the early 20th century electric motors had replaced animal traction at both installations, and a further round of upgrades in the mid-20th century adapted the network to the farming needs of the time.

How do you get there?

The site lies about 500 metres upstream from the main road, along the ravine, and is reached by a track that climbs the right side of the gully. It sits on private land, so visitors can walk through but should stay respectful of the property — access is permitted, not guaranteed as a formal amenity.

Why is it worth a stop?

Few places let you see, in one short walk, the entire arc of irrigation technology used along this stretch of Almería's coast: an animal-turned wheel, a gravity-fed canal, and an electric pump, all built around the same two reservoirs. Despite repeated modifications over the decades, the ensemble remains in good overall condition and offers a compact, physical record of how water — and the grape trade it fed — shaped this corner of Huércal de Almería.

Frequently Asked Questions

What is the Las Calabazas hydraulic ensemble? It is a pair of historic water-extraction installations — norias, reservoirs, and channels — built to irrigate vineyards near Huércal de Almería.

How old is it? The oldest parts, the animal-powered norias, date from the mid-19th century; later stages, including the arrival of a canal and electrification, run through the late 19th and first half of the 20th century.

Can visitors go inside? Yes, the site is accessible, though it stands on private land, so visitors should be considerate and careful.

What should you look out for first? The masonry drum of the eastern noria, about 10 metres across, the two circular reservoirs, and the underground gallery connecting both installations are the most striking features.
