Wetzlar in Hessen, Central Germany, is a former Free Imperial City, owing much of its fame to being the seat of the Reichskammergericht (Imperial Supreme Court) of the Holy Roman Empire. It straddles the river Lahn and lies on the German Timber-Frame Road on the north edge of the Taunus mountain range. It’s known for its old town and its medieval cathedral. Notable features include the Eisenmarkt and the steep gradients and tightly packed street layout of a medieval town. The sandstone cathedral of St. Mary was commenced in the 12th century as a Romanesque building. In the later Middle Ages the construction was continued in Gothic style. The church was never finished, as one steeple still remains uncompleted. The cathedral suffered heavy damage in WW2 from aerial bombing, but was restored in the 1950s.
