The study, conducted within UNESCO's Etna Park, highlights the effectiveness of specific vegetation indices—particularly the Normalized Difference Vegetation Index (NDVI) and Simple Ratio Index (SRI)—in identifying subsurface structures despite challenges posed by geology and spontaneous vegetation. By analyzing pre-excavation imagery from 2015, researchers identified the Near-Infrared 1 (NIR_1) and Red Edge bands as most useful for archaeological investigations. The study emphasizes the feasibility of low-cost, open-source software (FOSS) approaches in landscape archaeology, offering a scalable method for future research.

The Maritime Museum of Denmark, relocated to Elsinore's harbor front in 2013, strategically positioned maritime history as both a reflection of Danish cultural heritage and a forward-looking institution. Designed by Bjarke Ingels, the museum's new location—just steps from Kronborg Castle—amplified its role as a national symbol, embedding the shipping industry into Denmark's broader historical narrative. This architectural and curatorial endeavor, funded by a consortium of Danish foundations, received international acclaim for its innovative design and its ability to convey the relevance of maritime activities to contemporary society. The study highlights how such institutions can serve dual purposes: preserving historical narratives while simultaneously legitimizing and promoting an entire industry.

The discourse of French national identity is deeply intertwined with the historical practice of collecting and preserving ancient antiquities, particularly during the Renaissance. This study reveals that while such collections initially served as decorative elements in royal palaces like Fontainebleau, Saint-Cloud, and Versailles, they also symbolized social status and cultural sophistication. The transition from mere decoration to systematic preservation began with legislative measures during the French Revolution, notably the 1790 decree by the National Constituent Assembly, which prohibited the destruction of immovable and movable works of art in former royal estates. This legal framework marked a pivotal shift towards the protection of cultural heritage, reflecting broader societal values and the evolving role of monuments in shaping national identity.
