Quedlinburg is a northern German town known for its medieval streets lined with half-timbered houses. Overlooking the city is Quedlinburg Castle. The castle complex includes Romanesque-style Church of St. Servatius, which houses the tomb of 10th-century German king Henry I. The Schlossmuseum displays thousand-year-old artifacts. From the town, the Selke Valley Railway travels along cliffs, meadows and vast forests.
