Historic Roofless Masonry Structures: The role of Environmental Factors that Contribute to Decay and Collapse

Heritage roofless structures, while being invaluable heritage assets, face considerable risk of deterioration. This risk is usually increased when there is extensive water ingress and moisture in the structure. This paper focuses on masonry heritage buildings and ruins in England and has stemmed from an extensive literature review to identify recurrent causes of the disintegration of these structures. Researchers from the University of West London have processed the available literature to create a database that identifies taxonomies of buildings and scientific paths relating to ruinous historic structures. The paper concludes with recommendations for future research, focusing on the acquisition of additional data on the behaviour of masonry structures under varying environmental conditions, emphasising the potential implementation of advanced non-destructive testing techniques.

Analysis of hypogea environments based on ambient vibration data: application to a case study on the Palatine hill

We analyzed ambient vibration data, to rapidly identify the seismic response of an hypogea environment. The study area, is located on the Palatine hill and it is part of the Domus Tiberiana, originally built by Nero emperor. The underground cavities threaten the preservation of this important cultural asset. We used different techniques, including Horizontal to Vertical Spectral Ratio (HVSR), Power Spectral density (PSD) and Cross-Power Spectral Density (CPSD) analyses of the signals. The results demonstrated that noise measurements may be very effective for a rapid screening of cultural heritage sites and contribute to their seismic protection, by allowing for detailed identification of spatial variation of ground motions. Data was acquired in the framework of the CALIGOLA project, funded by the Lazio Region and the Italian Ministry for Research for the Technological District for new technologies.

Reconstructing Galileo’s Inclined Plane Experiments: Problems of Time Measurements

In this paper, we describe the recreate Galileo’s experimental setup to explore the dynamics of motion along an inclined plane. We not only replicate the physical measurements of distance and velocity but also emphasize the critical role of accurate time measurement, as used by Galileo to decipher the laws governing natural motion. In addition to reproducing the experiment using instruments available in Galileo’s time, this article presents a comparative analysis of the motion using modern tools: a video analysis application (Tracker) and an audio analysis application (Audacity).

The Theatre of Marcellus: between historical memory and digital innovation

This study presents an integrated research initiative on the Theatre of Marcellus, combining archaeological, architectural, and digital methodologies. The project investigates the site’s historical evolution and sociopolitical significance within the Campo Marzio through a multidisciplinary approach. A detailed 3D laser scanning and photogrammetric survey supported documentation and modeling efforts, enabling critical interpretation and digital reconstruction. The study emphasizes modeling strategies for restoration analysis, lighting simulations, and heritage communication. The resulting 3D repository serves both scientific and public engagement purposes, offering a dynamic platform for interpretation and preservation of one of Rome’s most iconic architectural and urban landmarks.

Dust Detector for Museum Environment Based on Raspberry Pi

Using a Raspberry Pi, we have created a low-cost, easily implementable, scalable and highly integrable system, suitable for real and extensive applications for dust detection within museum environments. In order to catch the dust, the Raspberry Pi uses a high-definition camera module on which dust settles. After the acquisition of the image, the platform is able to recognize and to cluster the single particles using a custom-developed image recognition software that runs on the Raspberry. The first analysis and consequent results are promising.

Post-earthquake structural assessment using Ground Penetrating Radar (GPR): preliminary insight for guidelines from literature review

Ground Penetrating Radar (GPR) is a Non-Destructive Testing (NDT) technique for quick and reliable post-earthquake structural assessment of buildings. GPR allows for identification of internal, hidden damage like cracks, voids, delaminations, and measurements of reinforcement integrity, which are often missed by visual inspections. Effective use of GPR depends upon careful planning, such as proper selection of antenna frequency depending upon the target and material being analysed. Though prompt and flexible, GPR has limitations such as shallow penetration in conductive targets and complex data interpretation. Therefore, integration with other NDT techniques can be required for a comprehensive and reliable building diagnosis. Standardized guidelines can support the reliability and effectiveness of GPR use in post-earthquake assessment. In this perspective, the article aims to provide some initial results through the analysis of literature in the field.

Virtual reconstruction of the Ducal Palace of Oliveto Lucano (Basilicata, Italy)

The reconstruction of the Ducal Palace aims to create virtual models, seeking a synthesis between technical data restitution and a naturalistic and evocative rendering of the architectural context. Generally, to create three-dimensional models, it is essential to have graphical drawings of the sites that will be represented with 3D computer graphics. Various survey methods can be used to produce these drawings, or data from surveys already carried out in the past on the architectural context can be used. In the case of the context presented in this work, the starting point was the scale plan of a cadastral map from the 1940s and photographs taken on site, specifically of the sixteenth-century basement walls, which are still present since the palace was demolished in 1946 to make way for a square in front of the mother church.

ERT surveys at the Necropolis of Baucina (Palermo)

The archaeological site of Monte Carrozza and Monte Falcone dominates in the south and east of the modern town of Baucina. These are two reliefs of modest size, separated by a small hill elongated in an East-West direction where the cliffs stand the necropolis. On these hills, probably in the sixth century. B.C., settled people, sicane that at the end of the century came into contact with the Greek colonies of Himera and the Punic Soluntum, as the research conducted in the last decade have demonstrated. Located in the hinterland, on the watershed between the river San Leonardo and Milicia, the sites are located in a critical point, in an area open to the connections between Palermo, Solunto and Himera. Archaeological excavations are conducted by the Chair of Ancient Topography of the University of Palermo, in agreement and cooperation with the Superintendence of Cultural Heritage of Palermo and with the logistical and financial support of the City of Baucina. Investigations affecting a sector of the cemetery located along the southern slope of Monte Falcone to combat the phenomenon of illegal excavations. For this purpose were undertaken, a series of geophysical surveys were. The survey results showed the presence of various structures, likely archaeological interest. Subsequent excavations made in areas investigated by geophysics have unearthed different funerary structures: burials in graves or nasturtium, cremation within pithoi or amphorae. The dead were accompanied by grave goods of the Greek tradition: skyphoi, achromatic cups, etc. Particular interest is a large tomb in an artificial cave entrance that consists of pillars and lintel plaster. The grave diggers violated by poachers is unique for their monumental architecture. It was reached by a corridor carved in the rock, in whose landfilling and numerous ceramic fragments were recovered a bronze coin.

Integrated Geophysical Prospection at the Roman Villa of Agosta (Comacchio, Italy): first results

This study presents the first archaeogeophysical results of the investigated area where the geophysical aim was the integratation of geomagnetic, ground-penetrating radar techniques. These environments, characterized by their unique geohydrological challenges, demand a tailored approach to subsurface diagnostics. This research assesses the potential of non-invasive surveys in enhancing archaeological understanding, especially in areas with prior excavation history. We focus on diagnostic sensitivity, data integration, and methodological adaptability under geologically complex conditions. The first results highlighted the multiple zones of magnetic anomalies, providing insights into buried structures and site preservation needs, and contributing tools for preventive archaeology and long-term monitoring. This research is part of a project funded by Patrum Lumen Sustine-Stiftung Foundation focused on advancing methodological approaches to archaeological geophysics in water-saturated coastal environments in Comacchio village (Roman Villa of Agosta archaeological site).
