Nístějka is a ruin of a castle in Vysoké nad Jizerou founded probably in the 14th century by the Waldstein family. In 1390, it was acquired together with the settlement of Vysoké by the Vartemberk family and in 1422 by the Jenštejn family. Around 1460, the castle was briefly held by King George of Poděbrady and his goods were attached to Návarov. Since 1519, the castle has been declared desolate, probably after a previous fire.[8]
The ruins consists of remnants of towers, walls and cellars on a narrow, long promontory over the Jizera river near Hradsko. The castle consisted of an elongated barracks protected by a moat and a cylindrical tower at its head, and a small inner castle where only a backyard with a tank and a rectangular palace was on the rocks.[8]
The castle is declared a protected area for the occurrence of herb Hackelia deflexa. In 1954, 1958 and 1972, archaeological research of the castle was carried out.[8]
