The “Männleinlaufen” (mechanical clock and glockenspiel, every day at noon) recalls the proclamation of the Golden Bull of 1356: seven Electors pay homage to Emperor Karl IV sitting on his throne. Richly decorated interior. The Tucher altar (ca. 1445) is considered the most important work of panel painting in the pre-Dürer period.
