The popular name of "barraques de vinya" or "barraques de pagès" should be observed in the field of rural architecture made with the technique of the dry stone" which includes huts, cisterns, borders, walls, wells and regugees of similar construction. The technique of the dry stone has been used by man for milleniums with aplications in cementery architecture, civil and militar. The use for the huts was shelter, and also to keep the heaviest tools for the fields when the fields are too far from home. The region of Subirats, due to its orographical peculiarities, has been suitable for the construction of this kind of huts, of which, even though they are not abundant, some can be seen at the zone of the hill of La Guàrdia and surroundings of Can Ros, the western side of the mountain range of El Pi del Molló, amongst other places. These huts were uses as a temporary farmer refugee and for the transport an labour animals in front of the inclemency of the weather. They were also used to keep the tools for the fields and as an occasional lodging for the workers of the fields For their construction, rather flat stones were used, placed one on top of the other. To fix it, smaller stones were used, and they were placed in rows and cilined outwards so as to allow the leakage of the rain water. Their walls are usually very thick. They were built by the farmers themselves using as their sole tool a hammer, to correct the shapes of the stones used in its construction. Those which still remain in Subirats, in good state, have a circular plant, both in the inside and in the outside. Interiorly, the dome begins from the bottom, it has a conical shape ending up in a great stone. The plant, specially the inside, is usually very irregular. The outside is usually well-finished and the roof is rather semi-spherical and it is covered with earth, where spontaneous vegetation springs. The access door faces south, generally with a great flat stone as lintel. The ground is earthy and the entrance door are very low for the present days, possibly due to the accumulation of earth caused by the rain and the wind. The weak point of the structure is the roof. When the water goes through it, the fast destruction of the hut begins. The vine-yard huts existing nowadays are suposed to date back to the end of the 18th century and until the beginnings of the 20th centyry, even though the ones in Subirats were built at the middel of the 19th century. They can be found at the lands of the furthest zones of population. They were used until almost recent times, until the time of the mechanization of the harvesting of the fields and the means of transport and locomotion. One must consider the vine-yard huts as real pieces of the architectural weath and of the popular art of the farmers, which besides playing a usefull role, they help shape the landscape of El Penedès.
