Nejdek Castle history is unclear. According to hypotheses, the castle was built from the end of the 13th century to the beginning of the 14th century. According to the feudal letter of 1341, the first documented castle owner was the knight Konrad Plick. At the beginning of the Thirty Years War the castle was probably still there and inhabited. In the course of the Counter-Reformation, rule came to Count Hermann Czernin in 1633. His nephew, Count Humprecht Johann Czernin, probably caused the old walls to be demolished due to disrepair and to use the building material to build the new castle in Neudek.
Today the tower and some fragments of original castle remains.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
