• The Role of Bacteria in Pink Stone Discoloration: Insights from Batalha Monastery

  Pink discoloration on the Ançã limestone of Batalha Monastery, a UNESCO World Heritage Site in Portugal, is primarily driven by bacterial biofilms producing carotenoid pigments. Key bacterial genera identified include Bacillus, Gordonia, Serratia, Methylobacterium, and Halalkalicoccus, with high-throughput DNA sequencing and culture-dependent methods revealing their role in biodeterioration. Biocolonization tests using stone mock-ups under simulated monastery conditions confirmed the link between bacterial activity and discoloration, offering critical insights for targeted conservation strategies.

• Biodegradation and Microbial Contamination of Limestone Surfaces: An Experimental Study from Batalha Monastery, Portugal

  Lichens significantly contribute to the biodeterioration of limestone at Batalha Monastery, Portugal, through mechanical penetration and chemical dissolution. The study used advanced microscopy (OM, LV-SEM + EDS) and X-ray micro-diffractometry (μ-XRD) to analyze stone fragments, while NGS metagenomic DNA testing identified bacterial communities within biofilms. Air quality monitoring revealed that sulfur, nitrogen, and phosphorus-rich pollutants may fuel microbial growth, exacerbating limestone degradation. This research highlights the complex interplay between biological colonization and environmental factors in cultural heritage preservation.

• Provenance study of the limestone used in construction and restoration of the Batalha Monastery (Portugal)

  A provenance study of the limestone used in the construction and restoration of the Batalha Monastery in Portugal reveals distinct sources for different architectural elements. Analysis using energy-dispersive X-ray fluorescence spectroscopy (ED-XRF), powder X-ray diffractometry (PXRD), and thermogravimetric analysis (TGA) identified that the baluster likely originated from the Valinho do Rei or Reguengo do Fetal quarries, while other components such as part of the church railing, north-aisle eaves arch, and Royal Cloister came from the Pidiogo or Cabeço do Roxo quarries. These findings were supported by Ca-Sr binary diagrams and petrographic evidence, providing insights into the historical construction practices and material sourcing of this UNESCO World Heritage Site.

• Surface orange patinas on the limestone of the Batalha Monastery (Portugal): characterization and decay patterns

  Orange patinas on the limestone of Batalha Monastery, Portugal, exhibit distinct compositions and decay patterns, suggesting diverse formation pathways. Analysis via μ-XRD and LV-SEM+EDS revealed that the ornament's patina primarily consists of gypsum with minor hematite, indicating possible intentional application as a tint plaster mixture of ochre and lime, while the window tracery's patina contains Ca-oxalates (weddellite and whewellite) with minor hematite, likely formed naturally due to atmospheric pollutants or bacterial activity. The ornament shows decay and delamination, whereas the window tracery exhibits granular decohesion without delamination. This study highlights the complexity of patina formation on limestone monuments and their susceptibility to degradation.

• Mineralogical and chemical characterization of surfa ce orange layers on the limestone of the Monastery of Batalha, Central Portugal

  A mineralogical and chemical analysis of orange surface layers on the limestone balustrades and sculptures of the Monastery of Batalha, Portugal, reveals that these patinas are primarily composed of gypsum and hematite, with minor components including halite and weddellite. This finding challenges the assumption that such patinas form naturally through weathering, suggesting instead that they may have been intentionally applied for protective or aesthetic purposes. The study employed X-ray micro-diffractometry (µ-XRD) and low-vacuum scanning electron microscopy coupled with energy-dispersive spectrometry (LV-SEM + EDS) to characterize the layers. These results are compared to 'scialbatura,' a common protective coating used in monument conservation, providing insights into potential historical techniques for stone preservation.

• The Influence of Environment in the Alteration of the Stained-Glass Windows in Portuguese Monuments

  Research reveals that environmental conditions significantly influence the alteration of stained-glass windows, with potash-lime silicate glass being the most susceptible to degradation. The study exposed soda-lime, potash-lime, and mixed-alkali silicate glasses in three Portuguese monuments—Monastery of Batalha, Monastery of Jerónimos (Lisbon), and Cathedral of Évora—for 10 and 20 months. Analysis using optical microscopy and Fourier transform infrared spectroscopy showed that crystalline deposits varied based on atmospheric conditions, with high humidity environments like those in Batalha and Jerónimos leading to more severe alteration layers. While the Cathedral of Évora exhibited dust and salt accumulation without severe chemical damage, the findings underscore the importance of environmental factors in preserving stained-glass heritage.
