Frauenkirche
Holy Roman Emperor Charles IV commissioned the late-Gothic Frauenkirche in 1350, and it was built on the site of a synagogue that burned to the ground during the 1349 pogrom. The modern tabernacle, designed to look like a Torah scroll as a memorial to that despicable act, was built beneath the main altar in 1991. The church's main attraction is the Männleinlaufen, a clock dating from 1509, which is set into its facade. The clock is one of those colorful mechanical marvels at which Germans have long excelled; every day at noon, the seven electors of the Holy Roman Empire glide out of the clock to bow to Emperor Charles IV before sliding back undercover. It's worth scheduling your morning to catch the display.
