This study examines the importance of microclimatic monitoring and non-invasive diagnostic techniques in cultural heritage sites for the identification of critical environmental conditions and the development of appropriate conservation measures. In particular, the research focuses on the microclimate analysis in the 'Sala delle Madri' of the Archaeological Museum of Capua, Italy, which houses a collection of important Roman and Greek sculptures. The study reveals that the microclimatic conditions in the ‘Sala delle Madri’ are not constant throughout the monitored year and the environmental parameter are influenced by seasonal variations and natural phenomena. A preliminary diagnostic investigation has been performed on the sculptures located in this room to document the state of conservation of the sculptures and to plan a specific analytical protocol aimed to characterization of both original and restoration materials, verifying the influence of the microclimatic conditions, due to high temperatures and NO2 levels. Moreover, X-ray fluorescence analysis (XRF) was performed on two archaeological coins to characterize the alloy composition and to document corrosion products and to understand degradation phenomena. This research highlights the necessity for the implementation of conservation measures to mitigate the negative impact of environmental conditions and prevent further damage to the archaeological findings displayed at Capua Museum. This study therefore contributes to the wider awareness of the importance of preserving cultural heritage and the role of monitoring systems in achieving this goal.

Protecting archaeological collections in Capua Archaeological Museum (Italy): The importance of microclimatic monitoring and non-invasive diagnostic investigations

The historical architectural heritage is often exposed to a high risk of damage due not only to natural events, but also to poor maintenance or neglect. In order to preserve it, it is necessary to conduct a series of multilevel and multidisciplinary studies capable of supporting the design choices for all the figures working in this field. The use of appropriate geomatic techniques and the choice of suitable sensors based on digital acquisition, allow the elaboration of accurate, high-performance 3D models with high quality photorealistic content. In this manuscript, a methodology is illustrated that, starting from the generation of a point cloud (TLS survey or integration of different digital sensors) allows the elaboration of an accurate 3D model for two different case studies from the point of view of architecture and survey data acquisition. In order to analyse these architectures from a structural point of view, the 3D model is optimised and transformed from a TIN model into a polygonal model (Quad-Mesh). This process represents a new approach in the management of complex architectures, capable of responding optimally to the computational capabilities for FEM (Finite Element Model) analysis, for the structural characterisation of the elements under investigation.

Digital technologies offer an effective solution for documenting and managing complex three-dimensional morphologies, particularly in the context of Underground Built Heritage (UBH). Our research explores novel digitization strategies by employing various technological tools for 3D scanning. We focus on a selected case study: the Grotta di San Michele Arcangelo. Range-based techniques using LiDAR-UAV (Light Detection and Ranging set in Unmanned Aerial Vehicles) were used for the cave’s exterior, integrated with SLAM (Simultaneous Localization and Mapping) technology was employed for the cave’s interior and close-range photogrammetry techniques captured intricate wall decorations. The results yielded precise geometric information crucial for subsequent three-dimensional modelling of architectural and natural spaces. Furthermore, these techniques were integrated to enhance information management, facilitate conservation efforts, and update existing documentation. The resulting comprehensive database is an essential tool for understanding, monitoring, and effectively managing these intricate underground environments.

Natural resins are among the multiple organic materials that have been employed since the prehistory as an adhesive or varnish in the manufacturing processes and operative chains of several tool. For this study, a black pitch sample found inside an amphora was compared with several types of natural resins previously analysed by gas chromatography-mass spectrometry (GC-MS). Different preservation states resins were collected or acquired to be analysed by GC-MS. The results obtained show the reliability and strength of the developed method, while also giving a hint about the raw material employed to coat the amphora.

Virtual modelling is a growing discipline which has become an important tool in the context of heritage preservation. From this point of view, its usefulness is not limited only to the reconstruction of artifacts and built structures, but it also can be an essential tool for the reconstruction of historical events. Utilizing virtual modeling it is possible to create an interactive educational experience aimed at a large audience. Praeteritas Urbes, in collaboration with the National Institute for Anthropology and History’s (INAH) Museo Regional de Palacio Cantón in Mérida, Yucatán led a multidisciplinary group of researchers in the reconstruction of an important historical event for the history of the colonial period in the Maya area: the Auto de Fe of Maní held on July 12, 1562. This article discusses the methodology and the workflow used to complete the project, starting from the architectural reconstruction of the former convent of St. Michael the Archangel in the Maya town of Mani, as well as the virtual recreation of the historical characters, the built space, and the recreation of the scenario of this historical event. An important part of this project involved the digitalization of the museum’s collection of archaeological pieces used for the special exhibition on the Auto de Fe of Maní entitled, Ídolos: Resistencias y Persistencias.

The creation of physical replicas of statues is not a novel concept; however, it continues to present various aspects worthy of investigation. On one hand, there is the need to optimize digital models for their physical experience while retaining distinctive features. On the other hand, there is the development of a robust pipeline for constructing reliable physical copies concerning morphometrics and materials. Both stages necessitate experimentation and comparisons, allowing for the validation of processes to achieve scientifically accurate results. This article, using the case study of the head of Sant'Elena preserved within the mausoleum of the same name, suggests comparing different processes of physical and digital 3D acquisition and reproduction of the artwork. The goal is to enhance its accessibility for individuals with visual impairments.

Building materials (BMs) can cause significant gamma dose indoors due to their natural radionuclide content. In 2013, the European Directive 59/2013/EURATOM introduced, in annex XIII, a list of types of BMs of interest for the content of gamma-emitting radionuclides among which materials or additives of natural igneous origin, such as granitoids, tuff and lava, are included. These materials have been largely employed for decorative and structural purposes in the course of centuries in the Italian heritage buildings. Aim of this study is to assess the contribute of BMs in terms of alpha exposure. Six samples of different materials, characterized in a previous study by the authors in terms of radiological content by means of a gamma spectrometry, have been analyzed in order to determine the specific exhalation rate of 222Rn, the radon emanation coefficient and excess in indoor radon concentration. Results confirm that BMs of natural igneous origin can play an important role in terms of alpha radiation dose and internal exposure due to the inhalation of the alpha particles emitted.
