The Veneziola Windmill, which still displays its spire and part of its machinery, was built very close to the sea to facilitate the transfer of water and propel it to the detection pools where it was left to evaporate, thus obtaining salt. Salt mill windmills typically have a height ranging form 8 to 12 meters. The diameter of their ciruclar base is between 6 and 10 meters. The upper part or roof is called the spire, and the blades that originated from it could measure from 10 to 14 meteres, and on them, sails were attrached. Similar to the boats of the local fishermen, these sails had a Latin shape, giving them one of their most distinctive features.

This mill does not have the typical windows along its body; instead, a single opening appears on the front face, which served as the entrance to the machinery. Originally, it must have been made of wood, and only the frame remains today.

In general, windmills consist of a series of wooden and iron gears that transmit the energy generated by the sails, driven by the wind. This one in La Manga preserves all that gear, and although not in very good conditio, it continues to attract the attention of numerous strollers. The introduction of modern systems in salt processing work led to the abandonment of these ancient systems, leaving them today exclusively as tourist attraction.
