LiDAR based investigation of subtle microtopographical proxy indicators: the case of Seluci Castle (Lauria, Basilicata)

The aim of this work is to investigate an abandoned medieval highland fortified site through LiDAR methodology. Much of the evidence that may have been preserved over time at sites of this type turns out to be untraceable for years through on-site survey activities. In the case of Seluci Castel (Lauria - PZ, Italy), the topography of the settlement, exclusively represented by the rectangular-plan tower located on the top of the mountain, was not clearly defined. The possibility of discerning the datum through LiDAR acquisition allowed to clarify and identify some of the fundamental elements that went to make up what can be considered not only a lookout and defense point such as Seluci Castle. Interpretation of the same data were helpful to further understanding of the site.
