One of the most complex challenges of heritage sciences is the identification and protection of buried archaeological heritage in urban areas and the need to manage, maintain and inspect underground services. Archaeology and geophysics, used in an integrated way, provide an important contribution to open new perspectives in understanding both the history of cities and in helping the decision makers in planning and governing the urban development and management. The problems of identification and interpretation of geophysical features in urban subsoil make it necessary to develop ad hoc procedures to be implemented and validated in significant case studies. This paper deals with the results of an interdisciplinary project in Cusco (Peru), the capital of Inca Empire, where the georadar method was applied for the first time in the main square. The georadar method was successfully employed based on knowledge of the historical evolution of Cusco and the availability of archaeological records provided by some excavations nearby the study area. Starting from a model for the electromagnetic wave reflection from archaeological structures and pipes, georadar results were interpreted by means of comparative morphological analysis of high amplitude values observed from time slices with reflectors visualized in the radargrams.

The Castle of Uggiano located in Ferrandina (MT),Italy, is evidently an emblematic example of fragile and inaccessible castle ruins within the landscape of the mediterranean coasts. The information of this architectural heritage appears fragmented and its ruins require early restoration actions due to its abandonment and the associated risk of disappearance. For this reason, a team of three architects, two engineers, a surveyor and an archaeologist were commissioned to carry out an executive restoration project by the Municipality of Ferrandina. This team proposes an integrated multidisciplinary methodology structured in the three main steps of data acquisition, data development and data dissemination, with the aim of identifying specific restoration project interventions and effective dissemination strategies. The systematization process of the data acquired by the archival and literature searches and UAV photogrammetry, allowed tocreate a detailed 3D digital model. This model was used to carry out remote site inspections, to develop studies of its historical building techniques and materials and toanalyse its specific structures, understanding their transformations over time, due to critical events such as landslides, earthquakes and sieges. The proposed methodology provides a dissemination strategy that develops along two parallel paths: the interactive fruition on Virtual Reality,through the use of an existing open-sourceweb platformfor tourism promotion, and the realization of innovative laboratory activities at the Elementary School to sensitize children to respect and care for the local historical heritage.
