The city of Wetzlar, located in the state of Hesse, Germany, is a former Free imperial city that owed much of its fame to being the seat of the Imperial Supreme Court (Reichskammergericht) of the Holy Roman Empire. Located at 8° 30′ E, 50° 34′ N, Wetzlar straddles the river Lahn and is on the German Timber-Frame Road which passes mile upon mile of half-timbered houses. Historically, the city has acted as the hub of the Lahn-Dill-Kreis on the north edge of the Taunus. The city is known for its ancient town and its medieval cathedral.
