The Sala Antica of the museum is characterised by a wall of 8 x 1.7 metres with double projection and tells the most ancient history of San Marino. From the submarine origin of the mountain to the legend of the founding saint, the visitor will witness a totally reconstructed 3D representation. The Sala Moderna is made up of a 1.5 x 2.5 metre model that faithfully reproduces the territory of San Marino. It was made with 3D printing and in a material suitable for video-mapping. An 86-inch 4K television displays ancient images, paintings, engravings and documents. In the Contemporary Room a double projection takes us through the period from the 17th century to the present day. The holograms of Santo Marino, Napoleon and Garibaldi were acquired via a sensor suit. An actor's movements and lip were then transferred to the fully reconstructed 3D models.
