The site of the 'Balsignano village' in Modugno (Italy), for some years has been the object of attention by scholars. Recently renovated, its valuation is nowadays the main objective for that Municipality. The aim of this article is describing our approach in integrating digital data, virtual tours and 3d models of the village elements to produce an interactive tool available on the internet, stimulating the desire to physically visit the settings. Our findings can be generalized to any context in which a link between a website and a physical site represent a challenge for low-budgeted Administrations.

The paper illustrates the results of a non-invasive characterisation of pigments and their mixtures in the pictorial surfaces of the wall paintings (10th century) found in the Byzantine church of Palazzo Simi in Bari (Italy). The investigation techniques included portable digital polarised microscopy, fibre optic reflectance spectroscopy (FORS) and X-ray fluorescence spectroscopy (XRF). Data comparison supported the recognition of red and yellow ochres, green earth, vine black, minium and Egyptian blue. The presence of some pigment mixtures demonstrated the recurrence of specific technical expedient used by local medieval artists in order to simulate more expensive pigments, which enabled contribution to the understanding of the valuable artistic tradition of the Apulian Middle Age. Both for purposes of conservation and fruition of the site, which is not always accessible, and due to the complexity in taking suitable photographs for the representation of results, the latter was performed on orthophotos extracted from a digital photogrammetric 3D model of the whole archaeological site. By means of chromatic overlapped layers, an interactive compositional map of the pictorial surfaces was produced.
