The documentation of built heritage involves tangible and intangible features. Several morphological and metric aspects of architectural structures are acquired throughout a massive data capture system, such as the Terrestrial Laser Scanner (TLS) and the Structure from Motion (SfM) technique. They produce models that give information about the skin of architectural organism. Infrared Thermography (IRT) is one of the techniques used to investigate what is beyond the external layer. This technology is particularly significant in the diagnostics and conservation of the built heritage.

In the year of the birth anniversary of the important Venetian artist, the paper aims to contribute to the great amount of studies conducted on the figure and work of Giovanni Battista Piranesi. After a brief presentation of the previous researches concerning aspects of the interpretation of Piranesian spaces, the contribution proposes a geometrical analysis of the "Veduta della fonte e delle spelonche d’Egeria fuor della Porta Capena or di S.Seb.no", collected in the "Vedute di Roma" (1748–1778).
