Siena: Centro Storico
Il Centro Storico di Siena (UNESCO 1995) è il museo vivente della pittura senese del Trecento — la città che negli anni 1280–1348 CE produsse Duccio di Buoninsegna, Simone Martini e i Lorenzetti in successione, rifiutò deliberatamente la prospettiva naturalistica di Giotto e invece portò all’estremo la sofisticazione cromatica e la spiritualità dorata della tradizione bizantina, e poi fu decimata dalla Peste Nera (1348 CE) proprio al culmine del suo sviluppo, preservando nel Palazzo Pubblico il più importante ciclo di affreschi laici del Medioevo europeo.
