• The brick material culture of Urbino (UNESCO World Heritage, Central Italy) as inferred from a multidisciplinary archaeometric study on the historic architecture

  A multidisciplinary archaeometric study on the brick material culture of Urbino, Italy, reveals that the city's historic architecture, from Roman to Modern times, relied consistently on raw materials sourced from nearby deposits. Thermoluminescence (TL) dating confirms the prolonged construction periods of key structures, including the Cathedral, which spanned over three centuries. The study highlights a progressive improvement in brick quality and preparation techniques, with firing temperatures reaching at least 850–900°C, though incomplete calcite breakdown due to inconsistent pyrotechnological processes. Uniaxial Compressive Strength of historic bricks aligns with modern standards, underscoring the enduring significance of Urbino's brick material culture, which continued seamlessly until the mid-20th century.

• What Does Intarsia Say? Materiality and Spirituality in the Urbino Studiolo ☆

  A groundbreaking analysis of the Urbino Studiolo reveals that intarsia, a form of wood inlaying, plays a pivotal role in infusing spiritual meaning into the secular palace of Federico da Montefeltro. The study demonstrates that the intarsia's materiality and motifs align with those found in ecclesial settings, creating a contemplative atmosphere within the studiolo. This finding refines our understanding of the city depicted on the eastern wall as a focal point for spiritual progression, guided by the intarsia-encrusted path. The research employs close examination to uncover the specific visual tradition informing this representation, offering new insights into the interplay between materiality and spirituality in Renaissance art.

• Ampliare un World Heritage Site verso il passato recente. L’opera di Giancarlo De Carlo a Urbino

  A proposal to expand the boundaries of UNESCO World Heritage Sites (WHS) to include 20th-century heritage, exemplified by Giancarlo De Carlo's work in Urbino, offers a novel approach to preserving modern architectural contributions. The study highlights that De Carlo's master plan for Urbino created a harmonious blend between modern architecture and historic preservation, enriching the site's cultural values beyond its original Renaissance focus. While the 1988 inscription of the Historic Centre of Urbino as an outstanding example of a Renaissance capital did not acknowledge De Carlo's work, the site's management plan (2012-14) suggests including modern buildings in the buffer zone. This raises questions about how to systematically integrate recent heritage into WHS frameworks, with potential implications for global heritage conservation practices.

• Urbino città Patrimonio UNESCO: un piano per la conservazione, valorizzazione e gestione del patrimonio storico – artistico dell’Ateneo

  A groundbreaking pilot project at Palazzo Albani, part of the UNESCO-listed Historic Centre of Urbino, introduces innovative protocols for conserving and communicating architectural heritage. The study, conducted by researchers from the University of Urbino, focuses on integrating historical archival analysis with direct investigation to identify optimal interventions. This approach emphasizes technical-constructive aspects while addressing the unique challenges of preserving non-renewable resources like Palazzo Albani, recognized for its irreplaceable value. The work aims to set a precedent for managing and enhancing the artistic and architectural heritage of Urbino's historic center, contributing to broader strategies for UNESCO World Heritage Sites.

• Geological Insights on the Calcareous Tufas (Pietra Spugna) Used as Building and Ornamental Stones in the UNESCO Historical Centre of Urbino (Marche Region, Italy)

  A groundbreaking study reclassifies the unique, porous carbonate stone known as 'Pietra Spugna' or 'Tufo spugnoso'—historically used in Roman architecture and later in Urbino’s UNESCO-listed historic center—as calcareous tufas. This classification, supported by physical observations and stable isotope analysis (δ13C and δ18O), sheds new light on the stone's formation process: chemical precipitation of CaCO3 driven by CO2 degassing from calcium-bicarbonate-rich waters, coupled with organic material encrustation in continental environments. Radiocarbon dating reveals these stones formed between 9100 and 4700 years BP, coinciding with the Holocene Atlantic climatic optimum—a period of peak carbonate deposit growth across Mediterranean regions and northern Europe. Ongoing research on a perched springline along the Metauro Valley suggests potential local sources for Roman-exploited blocks, offering insights into the provenance of Urbino’s architectural heritage.

• Participation and/or/ against tacit knowledge: ILAUD, 1976–1981

  A groundbreaking approach to urban planning and architecture emerged from the International Laboratory of Architecture and Urban Design (ILAUD) workshops held in Urbino between 1976 and 1981. These annual summer workshops, led by Giancarlo De Carlo, brought together students, educators, and practitioners to challenge formalism and explore equitable participation in urban design. While participants initially seemed divided—some emphasizing analysis of built fabric and cultural heritage, others advocating for direct user involvement—the research reveals these approaches were part of a broader consensus aimed at redefining the relationship between users, clients, and designers on the cusp of postmodernity. The study analyzes workshop outputs, including student work and lecture transcripts, to demonstrate how apparent contradictions actually contributed to a more inclusive and dynamic understanding of urban planning.

• The frieze of the Art of War in the Ducal Palace of Urbino: conservation issues, materials, and executive techniques

  A new analysis of the Art of War frieze in Urbino's Ducal Palace reveals key insights into its material composition, execution techniques, and conservation history. The study identifies the stone used—Calcare Massiccio A Formation (Piobbico Travertine)—and detects ancient ca-oxalate patinas, possibly from conservation treatments or biological activity. Autoptic examination clarifies the frieze's original conformation and carving process, while stylistic differences suggest multiple sculptors' involvement. The research also validates the most widely accepted hypothesis about the frieze's original arrangement on the palace facade.
