The Jesen Hospital is the only partisan hospital in the eastern part of Pohorje which has been restored. Its construction began in October 1944, and the first wounded soldiers were admitted on 6^th January 1945.

This partisan hospital is a complex of four small houses, which were used during the Second World War as a place for partisans to get medical help for those wounded in fights on Pohorje and its surroundings. The hospital has retained its original form and equipment; the only change made is that the houses have been given concrete floors for the purpose of easier maintenance. All the instruments the doctor and two medical nurses used in their work are also preserved here.
