The Unesco 14th Century Fortifications of Cerca Nova (Évora, Portugal): Provenience and Classification of Geo-Materials and Vascular Plants Inventory
The historic centre of Évora city (Portugal) is classified as UNESCO World Heritage Site since 1986. It is surrounded by fortifications built during the 14th century (Cerca Nova) and classified as National Monument since 1922. After their construction, at least five restoration interventions (15th, 16th, 17th, 18th and 19th centuries) were executed.In this research, a lithological characterization of the construction materials has been conducted.…
Aging of Limestones and Silane–Siloxane-Based Protective Hydrophobics: The Impact of Heating–Cooling and Freeze–Thaw Cycles
Stones are traditionally used in construction and architectural applications as building elements due to their aesthetic and technical/structural performance. Like other environmental factors (rain, humidity, moisture, salt presence, biological activity, etc.), heating–cooling and freeze–thaw cycles significantly threaten the longevity of stone materials. Hence, considering the socio-economic and cultural value of stones, preventive actions such …
Prospection of the Red Biological Patinas Influencing the Urban Scenery Architecture in Portuguese Territory
Portugal’s architecture reflects a rich history influenced by Roman, Moorish, Neoclassical and Romantic styles, with the 20th century marked by Art Deco and colonial influences. Regional styles vary, with white-painted buildings commonly experiencing color changes due to biofilm formation. Visually striking are the red-colored biological patinascommon in the coastal areas. A survey of 120 historical buildings affected by bio-colonization helps to…
Stone Endurance: A Comparative Analysis of Natural and Artificial Weathering on Stone Longevity
The long-term endurance of building stones must be assured since their longevity has repercussions for their economic and social value. Frequently, slabs for flooring and cladding are installed with polished finishing in outdoor environments for technical and ornamental purposes in cultural heritage sites and modern civil architecture. Compared to any other finishing, glossy surfaces are rather vulnerable to wear, particularly when they interact …
Climate change and its outcome on the archaeological areas and their building materials. The case study of Tharros (Italy)
Climate Change and Cultural Heritage: From Small- to Large-Scale Effects—The Case Study of Nora (Sardinia, Italy)
Rising sea levels are mainly due to increases in environmental temperatures that are causing ice to melt. The weathering of geomaterials is mainly due to the increase in the concentration of greenhouse gases in the atmosphere. This research addresses current and future sea level rises and their weathering effects on the building stones in the Phoenician–Punic archaeological area of Nora (Sardinia, Italy). Some forecasting models, selected accordi…
Micro Destructive Analysis for the Characterization of Ancient Mortars: A Case Study from the Little Roman Bath of Nora (Sardinia, Italy)
In this work, a protocol of a partially invasive sampling for the archaeometric characterization of ancient mortars from the little Roman Bath of Nora (Sardinia, Italy) is presented. Optical microscopy and different analytical techniques such as X-ray diffraction, X-ray fluorescence, thermo-gravimetric analysis, and physical/mechanical tests have been carried out on the mortars. These analyses were performed to investigate the chemical compositio…
The San Saturnino Basilica (Cagliari, Italy): An Up-Close Investigation about the Archaeological Stratigraphy of Mortars from the Roman to the Middle Ages
The manufacturing technology of historical mortars from the Roman to Medieval period apparently has not undergone evolutions. As reported in the literature, a quality decrease in the raw material occurred after the fall of the Roman Empire. During the Roman Age, the mortars presented the requirements of long durability due to hydraulic characteristics, and in later times, the production has only partially maintained the ancient requirements. To f…
The Islamic Ceramic of the Santarém Alcaçova: Raw Materials, Technology, and Trade
This study focuses on the analysis of Islamic ceramics from the Alcaçova of Santarém, Portugal. To establish the ceramic raw material provenance and ceramic technology, a set of raw materials was sampled and compared with the archaeological ceramics. Raw materials were dry sieved to increase the clay content, to reconstruct the ceramist homogenization process, and to evaluate chemical and mineralogical variation. Results showed that two raw mater…
