The first masters of the Nečven fortress were Nelipići, the owners of the entire Prominsko-Miljevac area. Owned by them until 1421, after which it came into the possession of the noble family Martinušić.

At the beginning of the 16th century, Nečven was conquered by the Turks, who owned it as a military fortress until 1688. In the middle of the 17th century, Nečven, along with Šibenik and Knin, was the most powerful and militarily and strategically most important fortress on the left bank of the Krka River.

Opposite the Nečven fortress, above the Krka canyon, is the Trošenj fortress, and its rulers were the Croatian princes Šubići. Both fortifications are today valuable monuments of Croatian cultural heritage. They were connected by a wooden bridge from the 14th century, which was demolished in the middle of the 17th century by Don Stjepan Sorić during the liberation from the Turks. After the departure of the Turks, Nečven was set on fire and half destroyed.

Since September 2011, systematic archeological research and conservation works have been carried out on the medieval fortress Nečven, as well as preparatory works for the future construction of a suspension pedestrian bridge over the Krka canyon that will connect the fortifications Nečven and Trošenj.

Krka National Park is located in the Šibenik-Knin County and covers an area of 109 km2 of the most beautiful course of the Krka River and the lower reaches of the Čikola River. It was declared a national park in 1985, while some parts of the Krka River have been protected since 1948.

With the submerged part of the mouth, the Krka is about 72.5 km long, and the 22nd longest river in Croatia. It springs at the foot of the Dinara mountain, 3.5 km northeast of Knin. With seven travertine waterfalls and a total drop of 224 m, Krka is a natural and karst phenomenon. The travertine waterfalls of the Krka River are a fundamental phenomenon of this river.

The area includes the Croatian part of the Dinara, Troglav, and Kamešnica mountains, the source and upper part of the Cetina river and karst fields along the Cetina – Hrvatačko, Paško, and Vrličko.
