Weisser Turm Castle

The White Tower in Weißenthurm, Rhineland-Palatinate, is a residential tower that served as a customs station and marked the border between the Electorate of Trier and the Electorate of Cologne. Its light plastered facade gave the tower and later the settlement its name.
History+
Although the White Tower is first documented in 1550, architectural findings suggest its construction in the early 15th century, likely under Archbishop Werner von Falkenstein of Trier. It was a part of the Trier landwehr and allowed for defense with firearms. Its location marked the border between the Electorate of Trier and the Electorate of Cologne. Around 1650, settlement began in the surrounding area. The town of Weißenthurm received market rights in 1663. The tower also functioned as a customs tower, where land tolls for the Electorate of Trier were collected at its base, secured by a ditch and a barrier bridge.
