The "Death valley" is a designation of the area in the valley of Kapišovka stream. During the World War II, in this area, in the period from the 21st to 27th of October 1944, heavy fighting took place, which were part of the Carpathian-Dukla operation. The fights were taken directly by the villages Dlhoňa, Dobroslava, Havranec, Kapišová, Kružlová, Nižná Pisaná, Svidnička, Vápeník and Vyšná Pisaná, all of which belong to the "Death valley".
In the valley of the Kapišovka river, as many as 11 000 soldiers died on both sides during these fights. Between Nižná Pisaná and Kapišová, destroyed T-34 tanks were left in the places, where enemy anti-tank weapons reached them.
