The riuraus are constructions that appeared in the Valencian area during the 18th century. They are linked to the boom period of the production of raisins, which occurred mostly during the 19th century, which was also a period of general economic growth. This construction was an essential element during the traditional process of making raisins. The function of these buildings was to serve as a shelter for the “canyissos” (the trays made out of reeds upon which the grapes were spread out so as to dry) whenever the rain or the night dew threatened to wet the grapes and make them rot.

In Llíber the riuraus route covers a distance of 2.3 km, with an easy level of difficulty. Some of the riuraus that you can see are those of Juan José, Sequer Gancho, Paco Guarero and Riurau de la Nota, amongst others.
