Charlotte Buff lived in this handsome 17th-century house — formally the Deutschordenshof, headquarters of the Teutonic Order in Wetzlar — where her father was the local steward. Several rooms have been kept as a small but evocative literary museum: Lotte's bedchamber, the salon, period objects, manuscripts, and a wall of Werther editions in 30-odd languages.
The museum is unmissable if Werther means anything to you, and quietly interesting if it doesn't — it captures the way one short novel reshaped European Romanticism. Closed Mondays.
