Space, power and culture have been adopted as transversal axes that cross the Middle Ages to carry out detailed study of medieval society and allow in-depth study and analysis, enriched by the interdisciplinary nature of the researchers, also permitting the material to be tackled through the combination of the different contributions (history, art, philology, music and thought) and also the different hermeneutic paths, with special attention to documentation, archaeology, textual analysis and the study of artistic objects.
