Krško (; ) is a town in eastern Slovenia. It is the seat of the City municipality of Krško. The town lies on the Sava River and on the northwest edge of the Krško Plain (), which is part of the larger Krka Flat (). The area is divided between the traditional regions of Styria (territory on the left bank of the Sava) and Lower Carniola (territory on the right bank of the Sava). The entire municipality is now included in the Lower Sava Statistical Region. Slovenia's only nuclear power plant, the Krško Nuclear Power Plant, lies southeast of the town. Name The name of the settlement was changed from Krško to Videm–Krško in 1953. The name Krško was restored in 1964. In the past the German name was Gurkfeld. History Archaeological evidence shows that the area was settled in prehistoric times. Along the Sava River, numerous Bronze and Iron Age sites as well as Roman finds show continuous occupation. After the Medieval period the area was a Habsburg possession. It was affected by Ottoman raids from the 15th to 17th centuries. Mass grave Krško is the site of a mass grave associated with the Second World War. The Bunker Mass Grave () is located on the steep right bank of the Sava River, opposite the municipal headquarters, north of the house at Bohoričeva 4, and south of a school playground. According to statements from the Krško police, it is believed that more than 100 civilians, mostly Croatians, were murdered in an abandoned bunker and the bunker was then dynamited. The location has been precisely defined, and investigation of the site is needed.
