Continuity, Resilience, and Change in Rural Settlement Patterns from the Roman to Islamic Period in the Sicani Mountains (Central-Western Sicily)
A new study reveals how rural settlement patterns in the Sicani Mountains of central-western Sicily evolved from Roman to Islamic periods, highlighting dynamics of continuity, resilience, and change. Strategic location between Palermo and Agrigento played a pivotal role in communication networks across these eras. The research integrates archaeological fieldwork with GIS-based spatial and statistical analyses, incorporating topographic (elevation, slope, aspect, TPI, distance to water) and ecological factors (vegetation series). This approach elucidates the complex transition dynamics from Roman settlement systems to Islamic landscape formation, offering insights into the interplay between historical developments and environmental factors in shaping rural landscapes. The findings contribute significantly to understanding the long-term impacts of cultural and environmental changes on settlement patterns.
New discovery of an ancient building in Akragas (Valley of Temples, Agrigento, Italy) through the integration of geophysical surveys
A new discovery of buried building remains in the Valley of Temples, Agrigento (ancient Akragas), has been made using advanced geophysical surveys. The study, conducted over a 3,000 m² area north of Plateia I-L, employed non-invasive techniques such as Electromagnetic (EM) surveys and Electrical Resistivity Tomography (ERT). These methods revealed subsurface anomalies indicative of buried structures, which were later confirmed through archaeological excavations. A wall constructed with large calcarenite blocks was uncovered, suggesting the presence of a building from the Hellenistic or Classical period. This discovery is significant as it may represent part of a larger, more complex structure near the entrance of the 'circular altars' sanctuary, potentially playing a vital role in Akragas's religious topography.
New researches on Pottery workshops in Akragas. Excavations in the artisanal area outside Gate 5 (excavation 2019)
Recent excavations at the Archaeological Area of Agrigento have uncovered significant insights into the pottery production of ancient Akragas, particularly outside Gate 5. Researchers from the University of Bologna, in collaboration with the Archaeological and Landscape Park of the Valley of the Temples, identified two previously unknown kilns (D and E) within a sector of the city's kerameikos quarter. This area, located near the Hypsas river and the sanctuary dedicated to the Chtonian Deities, was known for its three kilns (A-C), but this study expanded the understanding of its craft activities. The workshop produced Greek-Western amphoras, banded pottery, plain ware, tiles, and terracotta figurines, offering a glimpse into the colony's dynamic production during a period of growth. Non-invasive surveys (2017-2018) and excavations (2019) were employed to systematically investigate this artisanal zone, providing valuable data on the organization and output of Akragas' pottery workshops.
3D Modeling of Two louteria Fragments by Image-Based Approach
A groundbreaking digital approach has successfully reconstructed and analyzed two small fragments of louteria, a large terracotta vase from the Greek colony of Akragas (modern-day Agrigento, Sicily). By employing high-precision 3D modeling techniques based on image analysis, researchers achieved unprecedented detail in documenting these archaeological artifacts. The resulting models revealed intricate decorative features and geometric characteristics that were previously obscured or challenging to study. This method not only preserves the fragments digitally but also provides a new framework for interpreting and understanding their historical significance within the UNESCO-listed Archaeological Area of Agrigento.
A survey on the digital enhancement of the archaeological sites on Google and a multimedia pilot project in the Agrigento Valley of the Temples in Sicily (Italy)
A pioneering digital enhancement project at the UNESCO World Heritage Site, Agrigento Valley of the Temples, has successfully mapped the Temple of Juno Lacinia, making it the first Greek temple globally accessible via a 360° online tour on Google platforms. This initiative introduces interactive features such as clickable points of interest, accompanied by descriptive sheets detailing architectural and decorative elements, capitals, columns, 3D reconstructions, videos, and aerial virtual tours captured using drones. The project, currently in its pilot phase, aims to expand this immersive experience to the entire valley, offering multilingual (Italian and English) and audio-guided content. This approach not only preserves and showcases the site's cultural heritage but also sets a precedent for digital preservation and accessibility of archaeological sites worldwide.
Estrazione e raffinazione dello zolfo e paesaggio nella Sicilia romana tra IV e VI d.C.
Recent archaeological and historical evidence has redefined the chronology of sulphur extraction and refinement in the Agrigento region, Sicily, dating its peak activity between the late 4th and 6th centuries AD. This period saw significant sulphur production, primarily for agricultural use, particularly in viticulture to combat fungal diseases, which strengthened economic ties with Rome and other Mediterranean regions. The study highlights the transformation of mining landscapes during Late Antiquity and the Byzantine era, suggesting that Agrigento's role as a fiscal center may have diminished due to the rise of other centers. By analyzing historical sources like the Tabulae sulphuris and archaeological remains, researchers provide new insights into the commercial and cultural exchanges linked to Sicily's 'solfifera' area, emphasizing its broader significance in ancient trade networks.
Towards a new definition of ancient Akragas' urban grid. Preliminary contribution for a new image of the city
A groundbreaking redefinition of ancient Akragas' urban grid challenges the long-standing 1958 model proposed by Griffo and Schmidt. Through collaborative research involving the Archaeological Park of Agrigento, Politecnico di Bari, University of Catania, and Kore University of Enna, scientists E. Brienza and M. Liuzzo analyzed ancient street patterns in the upper Agora, reconstructing the city's lost architectural landscape. This preliminary study introduces a novel planning scheme that significantly differs from previous interpretations, offering fresh insights into the spatial organization of this UNESCO-listed archaeological site.
Integration of constrained electrical and seismic tomographies to study the landslide affecting the cathedral of Agrigento
Integrated geophysical techniques reveal the complex subsurface structures underlying landslides at Agrigento's Cathedral of Saint Gerland, providing critical insights for stabilization efforts. The study combined 2D electrical resistivity tomography (ERT), seismic refraction tomography (SRT), microtremor analysis, and surface wave soundings to map lithological layers, fractures, and cavities affecting the hillside. By constraining geophysical data with stratigraphic information from boreholes, researchers constructed robust 3D models of electrical resistivity and P-wave velocity, elucidating the sliding processes that threaten the cathedral and adjacent Archaeological Park. These findings offer a foundation for targeted landslide consolidation works to preserve this UNESCO World Heritage Site.
