The Reclau Caves, which form part of the Serinyà Prehistoric Caves Park (Pla de l’Estany, Girona), are shelters formed by waterfall travertines which have been in turn affected by karstification phenomena. Though relatively small, these cavities were big enough to held human occupation. Its evolution has seen the falling of blocks and infilling of terrigenous materials. Thus, the caves were completely filled and had most of their original roofs fallen. The first excavations of these caves were made in the mid 1940s and they continued, albeit with some interruptions, until present times. The caves were occupied by humans since the late Middle Pleistocene until the Holocene. Hence, the main occupation periods can be attributed to the Middle Paleolithic and Upper Paleolithic cultures. Given the existence of these sites, the project of an archeological park was started and its first phase opened to the public in the summer of 1997. The creation of this park has led to the protection of the three main caves of the site (Arbreda, Mollet and Reclau Viver Caves). The caves have also been adapted and singposted to open them to the public. Other facilities of the park include a reception building and an activity area. The caves can be visited in guided tours which include the projection of a film, the visit to the permanent exhibition room, the three main caves and the participation in some prehistoric-related activities

Ressenya del llibre Ullastret: guía de las excavaciones y su museo. Ullastret és un dels pocs jaciments que reuneixen les condicions òptimes per a ésser visitat. Però, per tal que sigui ben profitosa, calia oferir al visitant una guia que expliqués les principals característiques del lloc i el llibre de l’Aurora Martín ho fa

Debido a la gran cantidad de muestras arqueológicas impregnadas con PEG que se encuentran contaminadas por compuestos insolubles de hierro, se plantea la posible extracción y formación de complejos Fe-L (L=PBTC) y sus efectos en (i) la estructura de la matriz orgánica, (ii) la estructura y propiedades físicas del PEG y (iii) el comportamiento de la muestra en la etapa posterior de almacenamiento. El proyecto analiza la formación de compuestos químicos y posibles modificaciones estructurales en el proceso de extracción del hierro. Consiste en un estudio sistemático de un sistema químico y su influencia en los procesos de precipitación de Fe3+ en medio acuoso. El proyecto se fundamenta en: (1) desarrollar un proceso experimental de optimización para la extracción de las sales contaminantes y (2) encontrar las técnicas analíticas óptimas que permitan apreciar modificaciones estructurales de los diferentes sistemas. Se determina la cantidad de hierro extraído mediante A.A. Las interacciones entre PBTC y PEG se analizan por IR. Las modificaciones de determinadas propiedades físicas se determinan por DSC y las estructurales mediante SEM. En las condiciones termodinámicas óptimas se obtiene una extracción superficial del hierro (30-35%). La disolución del PEG origina modificaciones de la masa y el volumen de la muestra

The first protective activities of historical and archaeological heritage in the province of Girona (Catalonia, Spain), although some earlier precedents, were produced from the third decade of the nineteenth century. These arose as a reaction to this terrible destruction suffered as a result of the introduction of the liberal state and the disappearance of several regular orders. Preservationists actions were carried out by some pseudo-public entities, which acted at the request of local authorities. These entities include the the Diputación Arqueológica, the Sociedad de Amigos del País and the Comisión de Monumentos. These corporations, with significant human and economic constraints, began activities as important as the beginning of the excavations of the site of Ampurias, the formation of a provincial museum in Girona and the restoration of the monastery of Ripoll.
