Located in the natural area of La Flecha del Rompido, the Real de la Almadraba was built in 1929, following four centuries of the art of tuna fishing on the Huelva coast. The complex consists of three distinct areas: a camp-like area formed by a series of sheds where the Almadraba workers lived, the Captain’s House, and a group of industrial pieces essential for maintaining fishing gear. This includes the dock, the diesel shed, the tar melting boiler and its chimney, and the tarring area. The Real de la Almadraba was abandoned in the 1970s and declared a Cultural Interest Property (BIC) in 2015^1.

The intervention focuses on the industrial pieces and is complemented by a new pedestrian path connecting the mouth of the Piedras River and the Atlantic Ocean. The rehabilitation is divided into two areas: the dock and the diesel shed, of which only traces remained, and the boiler, chimney, and tarring area, which, although in better condition, required significant intervention. The dock was a floodable piece built with local stones as a dike. The extremely challenging construction conditions, subject to the tides and complex supply conditions, led us to rebuild the dock using a technique similar to the Roman style: based on the trace of the old dock, using its remains as a foundation, a perimeter wall of cyclopean concrete with local grauwacke stone was built in layers that took advantage of low tide for their placement. These walls, reinforced with fiberglass instead of steel to prevent corrosion, are braced by a lower and an upper slab. This construction method, where concrete is poured in layers and then chipped away, forms a stratified, almost geological volume, closer to the origin of this type of dock and in harmony with the protected complex and the riverbank. Finally, the upper slab that forms the dock’s pavement is channeled using an in-situ mold that creates a herringbone pattern, a motif repeated in the Real de la Almadraba in the pavements dedicated to draining melted tar for recovery.

On the other hand, the rehabilitation of the boiler, chimney, tarring area, and drainer has been based on philological criteria, thanks to their state of conservation allowing the deduction of the constructive techniques and finishes they had presented in the past. Access to the boiler piece is from the channeled pavement of the dock that culminates in it; from this point, it is possible to understand the entire process of protecting fishing gear. The boiler, consisting of two furnaces and the chimney, is accessed via a staircase whose central area features a cushioning that allowed the ascent of tar barrels, which melted and passed to the tarring area where fishing arts were hung from a clothesline located between two pillars that descended towards the two melted tar wells with a pulley and were protected by pitch. Finally, the nets went to the drainer shed, where they were left to dry, and the excess melted tar was recovered through the channeled floor, now emulated on the dock. The rehabilitation has been carried out with ceramic pieces found on-site and with lime mortars and silicate paint that favor the breathability of the factories and give the complex an appearance that refers to its original state, where the white volumes, whose refined geometry stemmed from their strictly functional use, stood out in the landscape.

The third intervention in the realm of the Real de la Almadraba enables an accessible path between the two banks of La Flecha. The high scenic value of this protected natural site suggests implementing a reversible installation through a wooden pedestrian path that gradually enters the thick bush of broom and prickly pear. The geometry of this walkway results from overcoming the two powerful dune cords that precede the Atlantic Ocean, thus avoiding significant earth movements that would alter the existing landscape and excessive slopes that would prevent access for people with reduced mobility. The design of the walkway is based on usual industrial systems, although the dimensions have been modified so that the protection elements of the railing are also fastening, resulting in a more abstract element that crosses the landscape without denoting its scale and makes it difficult for pedestrians to access the natural site outside the walkway area, thus protecting the flora of rush, thistle, lily, and sea caterpillar and the nesting of harriers, storks, and little egrets.

The project on this protected architectural and landscape ensemble has sought to recover the industrial sense of the almadrabero process, thus revealing the heritage and ethnological legacy of a millennial fishing art that coexisted in harmony with the landscape of the Huelva coast.
