Kalnik is located on the border of Zagorje, Prigorje, and Podravina, about 80 km from Zagreb. Here visitors are greeted by a picturesque forest world, an educational trail, and the remains of two old forts. The smaller of them is located at the top of Mali Kalnik, and the larger one is on Veliki Kalnik. Veliki Kalnik has once even proclaimed a royal palace. This was during the reign of King Sigismund, whose wife Barbara of Celje, also known in legends as the "Black Queen", often came here. The city was first mentioned in the 13th century and consisted of three parts. The first one was built at the time of the Tatar invasion when King Bela IV hid in it for some time, with whom the legend of the Kalnik "plum growers" is connected. Namely, according to the legend, the inhabitants of the villages of Kalnik fed the king with their plums, which is why he granted them noble honors.
