This attractive Neoclassical cathedral looms above the quiet square. Built in 1797, it once featured stuccowork and frescoes by Franz Anton Maulbertsch and was supported by grand marble columns. Unfortunately allied bombing in the final days of WWII did not spare the cathedral, but the splendid interior has been restored with great care, featuring pink-marble pillars, a couple of Maulbertsch originals and a glorious red-and-white marble pulpit. A feature of great interest to those with a taste for the macabre is the glass coffin to the right of the entrance containing the remains of a mitre-bedecked saint.
