Hruboskalsko is a nature reserve declared on April 22, 1998. With an area of 219.2 ha, it is one of the largest rock towns in the Protected Landscape Area Český ráj. The reason for protection is the extensive rock town with preserved relict pine forests. The Hruboskalsko rock town includes hundreds of rock massifs and individual towers reaching up to 60 m in height. Due to the low resistance of sandstone and the constant effect of various influences, the rocks are rich in a variety of shapes and forms (honeycombs, windows, gates).

The castle was founded between 1260 and 1280 by the Markwartings. This family, from which several Bohemian noble families emerged, rose to prominence during the reign of King Otakar II Přemysl and owned extensive estates in the Jizera region up to the Giant Mountains. The first documented owner was Zdeněk (1280–1304), who named himself after the castle of Waldstein. He was the son of Jaroslav of Turnov (1234–1269). In addition to the castle, the Waldstein domain included several villages on both sides of the Jizera River, around Turnov, up to the Cistercian monastery of Hradiště. Even during Zdeněk's lifetime, disputes over ownership arose, which continued in subsequent generations. From 1318 onward, court proceedings between members of the Waldstein family for robbery in the associated villages are documented.
