In 1319 the construction of a castle under the foam castle began. With the construction of the Niederburg within the city in 1443, Balduinstein Castle became increasingly less important. After several phases of expansion of the castle in the 14th and 15th centuries and the connection to the city fortifications, decay began in the middle of the 17th century. After the end of the Thirty Years' War in 1648, the Elector of Trier granted permission to demolish in 1665, and in 1680 only the walls stood. In the 19th century, the ruined castle was used as a quarry.
