Scharzfels Castle is the medieval ruin of a fortification located east of the village of Scharzfeld. For centuries after its construction in the 10th or 11th century it remained an impregnable fortress. In 1761, during the Seven Years' War, a body of French troops, numbering some 6,000 men, appeared in front of Scharzfels Castle. After a 10 day siege they were able to capture the castle only to discover it was being held mainly by 250 invalids. After only four days' occupation the French blew up the castle and withdrew when it became known that Prince Ferdinand of Brunswick was advancing on Scharzfels. Since that time, the castle site has lain in ruins.
The castle is open all year and free of charge. There is a small cafe which is open Tuesday to Sunday 11.00- 17.00
