This is the name given to the old warehouse used for the transformation, cleansing and storage of sugar. It is one of the best examples of Valencian industrial architecture in relation to sugar-cane production. The building has a rectangular floor with three storerooms covered with two sloping roofs, and dates back to the mid-15th to the early 16th centuries.

Between the 15th and 17th centuries, there were some 23 trapiches (sugar factories) in La Safor, whose driving force was the traction animal who pulled the grindstones that crushed the sugar-cane. Oliva’s originality is that it was the first town where the technological innovation that led to building the Enginy was employed. The Enginy, which translates as ‘device’ or ‘contraption’, was a system where the traditional grinding stone was substituted by milling machinery moved by hydraulic energy, this increasing productivity.

The ‘mother canal’ crossed through part of the town and, taking advantage of the unlevel terrain, workers constructed a basin where the water ran into and could be employed to run the machinery. It was retained and then released, producing energy to work the mill that was used for crushing the sugar cane. It is because of this system that the Almacén del Enginy became the largest and most innovative sugar mill in the area.
