The ruins of the former Krka hydroelectric plan are found at Skradinski buk, in the very centre of Krka National Park.
It was constructed and began operations in 1895, just two days after Tesla’s hydroelectric plant on Niagara Falls became operational. At the same time, 11 km of power lines to transmit electricity and a city lighting network were built, the first complete electricity system in Croatia. Thanks to Šibenik Mayor Ante Šupuk and engineer Vjekoslav Meischner, Šibenik had electrical lighting before many European cities, including Vienna, Budapest, Rome, London and others. Ten years later, Ante Šupuk built a second hydroelectric plant, Jaruga, just a hundred metres downstream from the first. Following the installation of additional turbines in 1936, the plant is still in function today.
Due to the historical significance, the Krka hydroelectric plant is protected as a monument of industrial architecture. Restoration works are currently in place, aimed at conservation and presentation of the plant.
