NS-Ordensburgen
In Nazi Germany, the NS-Ordensburgen ("National Socialist Order Castles", singular Ordensburg), also called Schulungsburgen, were schools developed for elite Nazi military echelons. There were strict requirements for admission to the schools. Junker candidates had to be aged between 25 and 30 years old, belong to either the Nazi Party, the Hitler Youth, the Sturmabteilung, or the Schutzstaffel, be physically completely healthy, and be pure-blooded with no hereditary defects.
The schools themselves were typically stark, modern structures with extensive facilities. Vogelsang, for instance, reportedly contained the world's largest gymnasium at the time. Each student attended all four institutions in sequence, for specialty training, finishing in Marienburg for training that included live-fire military exercises.
The three institutions for education of political leaders and their educational focuses were:
