Here’s another one continuing the “trains and castles” photo series. Pictured are the ruins of the 12th century Burg Ehrenfels, while a DB Cargo train is seen passing underneath. The Archbishop of Mainz had this castle built, as a defense, but is also served as a customs post together with the Mouse Tower that was built in the Rhine river and is still in good condition today. The castle was destroyed by French troops in 1689 and stayed that way until today.
