Dry stone structures are sturdy and the construction technique is versatile and totally respectful to the environment. The stone is taken from the ground itself, it is not treated, and once the construction is completed it is unobtrusive and blends in perfectly with its surroundings. Furthermore, any structure that falls into disuse and becomes dilapidated becomes integrated, once again, with its natural setting.
Dry stone constructions were therefore already on site before they were built, and remain so once completed, something that makes them 100% sustainable and, according to the qualities of the stone that is used, they take their particular characteristics and their colours from the land they are built on.
For example, there are contrasts in colour between the clear white of the limestone used in El Camp de Tarragona, Central Catalonia, the districts of Girona and Les Terres de l’Ebre; the dark tones of the slate used in L’Alt Pirineu, L’Aran and L’Alt Berguedà; the red of the volcanic stone in the Pedra Tosca Park in La Garrotxa, the only place in Catalonia with constructions made with this kind of stone, and the Bundsandstein, or reddish coloured sandstone, typical of many constructions in the Baix Llobregat and other places.
