Rock art researchers describe the existence of a preparation layer of kaolin (with or without organic binder) on the rock, on which megalithic painting was carried out, using a mixture of pigment and binder. The natural pigments used were mainly hematite, ochre and carbon black. As binders, animal fats, blood, resins, etc. were reported. The uncertainty regarding the composition of these paintings means that there is not a clear procedure for their reproduction in the laboratory as mock-ups. This study shows a methodology based on the assessment of a group of parameters that allow assessing the suitability of a binder (in this case, butter or casein) both in the preparation layer and in the pictorial layer. Covering capacity, drying velocity, binding capacity, grip on the substrate and biological growth were evaluated. It was completed with colour spectrophotometry and scanning electron microscopy. The mixture of butter with pigment applied on a kaolin-based substrate was identified as the most suitable.

“Yo soy conservador porque siempre me ha parecido absurdo que los hombres anadan sus facultades intelectuales y su fuerza material al incesante trabajo de destruccion que realiza constantemente e implacablemente la naturaleza… Si todas las cosas estan destinadas a caer, porque esta es su ley fatal, lo mas razonable es apuntalarlas, si es posible” (Pla, 1968, 280)

The rock art necropolis of San Vítor de Barxacova (IX-X A.D.), located in Parada de Sil, Ourense (Spain) is found on a granite rocky outcrop that presents an enormous complexity for its conservation due to the multiple alteration mechanisms that affect the rock. That is why different studies, chemical, geological, conservation materials, etc., are being carried out to control their degradation on the surface, something that has already been achieved today on the surface. The present work tries to verify if by means of the study with GPR (Ground Penetrating Radar) it is possible to advance in the knowledge of the subsoil of the outcrop, of which its current state is unknown. This non-destructive technique, applied for the first time on an archaeological site of these characteristics and with such specific objectives, could help to better understand the degradation mechanisms that may exist under the surface and therefore prioritize efforts and methods of conservation of this archaeological site improving its diagnosis.

Abstract: this document seeks to describe and collect the treatments carried out in the barn of Lamas de Abade. The reason for the work and its transfer is due to the works of the AVE on its arrival in Santiago de Compostela. The work carried out consisted of a diagnosis and assessment of the state of conservation, cleaning and disassembly-reassembly of all the preserved parts. Damaged elements were also renewed.

San Vítor de Barxacova necropolis, from the 10th to the 11th century, in Parada de Sil (Ourense), shows a high level weathering of granitic rocks which has involved a great challenge for its conservation due to exposure to outdoor conditions in an environment with very complex degradation processes. Although, the first attempt was proposed as a preventive action, the wrong guidelines from the Administration Office for the Cultural Heritage of Xunta de Galicia compelled the design of an intensive curative intervention. This way of proceeding was determined by the set of mandatory standards in such an important heritage action. The holistic approach of this intervention, the exhaustive diagnosis and the extensive chemical analyses were the key issues which allowed the design of the best method of action to consider nowadays based on the use of new synthesized materials and analysis and treatments methodologies. The whole intervention was defined by its high complexity but, fortunately, the archeological site still remains alive since several restoration and preventive interventions have been made for the last six years and a maintenance protocol was signed, the first in Galicia, has been achieved in order to keep the attractiveness of this archeological site to all the visitors that arrive at this highlighted place. The investments made by different administrations involved in this project have tried to reverse in Parada de Sil the effort made all along these years.

Memory of the analysis, diagnosis and conservation work in the hillfort of San Tomé (Ourense, Spain). Some problems that affect conservation work are also detailed when archaeologists and administration intervene in this process (with diametrically opposed views). This problem occurs when trained professionals lead this type of intervention. That action, which is widespread in Galicia and Spain, is due to the lack of regulation (law regulating activities on cultural heritage, especially archeology) that recognizes the restorative's ability to lead these works.

Se presentan en esta comunicación los resultados más importantes de tres intervenciones arqueológicas de diverso alcance realizadas en diferentes momentos, entre 1993 y 2014, en torno a un mismo torreón de la muralla cristiana de Madrid, en la Plaza de Puerta Cerrada. Los trabajos han permitido documentar un torreón en buen estado de conservación, diversas intervenciones realizadas históricamente en la muralla y un acceso al adarve desde la torre estudiada.
