Princess Kunegunda is a heroine of the legends of Sudetes, and is said to have lived in Kynast Castle in Poland. To avoid marriage, she set a condition that her future spouse must complete a circuit along the castle's walls on horseback in armor. The particular difficulty of the task lay in the fact that the walls were narrower on the side of the castle bordering on a cliff. Many knights died trying to complete the task, until one of them accomplished it and rejected the love of the princess. In response, Kunegunda jumped over the edge.
