Matera (Basilicata, southern Italy) was awarded the World Heritage Site status by the UNESCO since 1993, and has been named the European Capital of Culture in 2019. It is one of the most ancient towns in the world, whose historical centre was totally built by a weakly lithified and highly porous lower Pleistocene sedimentary building stone, known as Gravina Calcarenite. This easily workable rock was quarried since prehistoric times, and it was used for building different kinds of constructions from the rupestrian settlement to gorgeous historic palaces during the XVIII century. Calcarenite,...

Nanosilica-based consolidants are promising nanostructured strengthening agents mainly used for consolidation of mortar and cements. Their use shows some positive aspects that encourage their application in stone consolidation field. Several preliminary studies underline that the nanosilica particles increase the reactivity and the penetration depth than other products having a great effect on silicate stone [1]. In this context, the aim of the present work is to formulate a specific nanosilica product suitable for the consolidation of Bianco Sardo, Pietra di Firenzuola and Pietra di Muggia....

The main goal of this preliminary study is to compare the effects of different consolidating materials on some marble and sandstone samples from Tuscany. The collected samples are divided into two groups, one of which underwent artificial weathering. A comparison on the physical properties before and after the application of the consolidating materials is given.

A project for realising replicas of a couple of marble statues starting from reality-based 3D models is being presented in this paper. It takes advantage of the SfM technique to produce realitybased models, and to FDM system to 3D print the replicas. The paper presents an overview of the potential of additive manufacturing systems in the field of cultural heritage conservation and describes all the phases of the project, up to the evaluation of the correspondence between the original and the copy.

The paper addresses some issues related to the acquisition of points clouds by Terrestrial Laser-Scanning, TLS and their elaboration with the aim to create structural models of masonry vaults. This structural system, existing in several artifacts and historical buildings, presents the advantage of having a good static and functional behavior, reduced weight and good requisites of insulation and aesthetic quality. TLS technique is well suited for the survey of geometric forms of monumental complexes, often realized with very irregular materials and forms. As case-study we illustrate a...

The paper shows, on an interesting study case, an application of the surveying technologies belonging to Geomatics and investigates the advantages provided by them to the Cultural Heritage field. The technologies analysed here are the digital photogrammetry and the 3D scanning, as they represent two very versatile and accurate solution in this field. Moreover, are presented the potentialities of the digital models obtained as they are suitable for both geometric and historic analysis of an object.

Purpose of this paper is to illustrate the contribution of geomatics studies in management and protection of Cultural Heritage assets. Architectural surveys, carried out by integrating traditional survey techniques with more innovative instruments, are fundamental to guide the different actors involved in conservation and restoration processes, as they allow them to get a complete and extensive knowledge of the survey object, at different levels of detail and scales of representation. The integration and elaboration of the different survey techniques are illustrated in this paper with...

This paper presents the preliminary results obtained through a geophysical survey realized in 2017-2018 in investigating the archaeological site of Monte Torretta (Pietragalla, PZ), one of the most interesting and less known settlements of modern Basilicata. The geophysical survey is part of the Pietragalla Project, an international research program led by the Université Paris 1 Panthéon-Sorbonne and the Humboldt-Universitat zu Berlin aiming at the study and the valorisation of the site. Through the comparison and integration of different geophysical methodologies, including Ground...

In this paper we present the results of a geophysical survey conducted using frequency domain electromagnetics (FDEM). The geophysical survey is part of a wider archaeological research project designed to obtain conclusive evidences about the location the Roman harbour expected to be buried under alluvial sediments in the bay close to the remains from Greek and Roman times. A total of 3545 stations were recorded with a Geonics EM31 MK2 ground conductivity meter in two dipole configuration modes: horizontal and vertical dipoles. Apparent conductivity measurements were sampled every meter...

The Santa Maria dellʼAlto tower in Nardò (Lecce, Italy) represents one of the many types of coastal towers of the ancient Terra d Otranto province. It was built between 1568 and 1569 becoming part of the defensive system of the Ionian coast of Salento against the Turkish threat. The architectural survey ad analysis of the tower allowed us to investigate constructive elements, wall discontinuities, additions, subtractions and functional modification in order to understand the phases and the change of the structure over the centuries. Digital photogrammetry and infrared photography have been...
