Abstract. In recent years research works have shown that augmented reality tools can offer effective support for the dissemination of architectural heritage, when integrated into the information data extracted with surveying and representation tools and further data from other sources, e.g., history.

The development and permanent updating of software platforms dedicated to augmented reality, i.e., Apple's ARKit and Google's ARCore, as well as the introduction of new features, offer today affordable support for the development of AR solutions.

Some operational difficulties are due to the rapid and constant evolution of the technologies; the available solutions can be compared to prototypes and the development of user experience effective solutions appears still lacking. The main subject in the construction of AR solutions is still linked to the development of effective methods to properly set up the visualization of 3D models and their interaction with the real scene. The chosen case study for the test of persistent AR solution for the visualization of works of art is the ‘Tribuna’, i.e., a monumental and sculptural marble apparatus, that decorated the main apse of the Cathedral of Palermo.
