The Cathedral of Arezzo, dedicated to Saints Peter and Donatus, crowns the highest point of the old town, a grand Gothic church begun in the 13th century with a soaring interior, fine stained glass and important artworks, including a small fresco of St Mary Magdalene by Piero della Francesca. Its imposing form and elevated position make it a landmark of the city. Visiting the cathedral, with its art and its atmosphere, is a highlight of exploring the historic centre.
