Urban Wunderkammer: Physical and Digital Experiences in the Historic Center of Turin

Through this contribution, the authors aim to illustrate a pathway for the knowledge, communication, and accessibility of urban heritage by utilising and applying current survey and representation tools based on AR technologies. Specifically, the area of focus is Piazza IV Marzo, located in the centre of Turin, whose original Roman layout has been modified over the centuries. Our research begins with a historical and philological study of the square, followed by the acquisition of metric data using a laser scanner. We then develop a three-dimensional reconstruction of the buildings through BIM processes, create a 1:500 scale 3D-printed model of the square, and conduct AR experience tests applied to the scaled model. Harnessing the power of augmented reality and interactive media, our prototype, Urban Wunderkammer, is an attempt to transform a “passive” informational experience into an active and exploratory one, with the potential to revolutionise the way we interact with and understand our urban heritage.
