Schneppenbach was administratively tightly bound with the Schmidtburg castle, which nowadays stands within the village's municipal limits. The castle, whose beginnings go back at least as far as 929, and possibly as far as 926, is one of the oldest in the Nahe-Hunsrück region and is believed to have been the family seat of the Counts in the Nahegau, the Emichones. Their coheirs and rightful successors, the Waldgraves, owned the castle in the 12th and 13th centuries. Internal Waldgravial family disputes, however, resulted in ownership being transferred about 1330 to Archbishop and Elector of Trier Baldwin of Luxembourg. Under Baldwin, the castle was expanded, and in the time that followed, it became the seat of the Electoral-Trier Amt of Schmidtburg.
The castle was destroyed during the War of the Grand Alliance (1688–1697) by French troops in 1688. Today impressive large ruins remain.
The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
