This paper shows how the application of geo-location tools facilitates the analysis of Jeanneret/Le Corbusier’s experience of medieval art and architecture during his 1907 Voyage to Florence. While Jeanneret/Le Corbusier’s 1911 Voyage is better known, his 1907 Voyage provides an opportunity to study the cross-historical influence of medieval art, architecture and urbanism on the development of Early Modernism. Methods of analysis that employ digital technologies allow for new explorations of this body of work. Geo-location tools are particularly applicable as they reveal patterns and themes that would otherwise go unrecognised. Several of these will be discussed as to their suitability in support of this research.
