One morning in the 18e century, a poacher has seen two men digging a hole in the ground. Then they puch in a young and beautiful bride in their weeding dress and buried her alive. The poacher called the master of the castle. They dig up the young girl. She was still alive but she died in the same day. The two meurderous was probably the brothers of the bride who didn't want this marriage. During long time, the bridal veil and bouquet was swown in the castle. Sometimes, the ghost of the bride can be seen in the castle.
