It’s Luther lore galore at the very monastery where the reformer lived from 1505 to 1511, and where he was ordained as a monk and read his first Mass. You’re free to roam the grounds, visit the church with its ethereal Gothic stained-glass windows and attend the prayer services. Guided tours of the monastery itself take in the cloister, a re-created Luther cell and an exhibit on Luther’s life in Erfurt. You can sleep here, too. Enter from Comthurgasse.
