A covered Wehrgang, or set of battlements, serve today as a bridge connecting the two halves of Burg Thurant, a 12th century German castle in Alken, on the Moselle, in spring 2017. After exchanging hands several times, the castle was besieged and captured by the joint forces of Arnold II of Isenburg, Archbishop of Trier, and Conrad of Hochstaden, Archbishop of Cologne, who divided it between them. Each half of the castle then functioned independently to each other, each with its own residences and defences. The Wehrgang connected a turret (pictured) in the Trierer Burg, or Trier Castle, with another in the Kölner Burg, or Cologne Castle, and was probably jointly manned by defenders from both forces during sieges.
