The Workshop will take place in Campus Hybernská, situated at the very heart of Prague’s New Town. A vibrant meeting point for students, academics (not only of Charles University) and general public, Campus Hybernská occupies a formerly abandoned complex on Hybernska street and still retains a raw, industrial feel.
