In Germany during the 3rd Reich, there were 38 so-called National-Political Educational Institutions (NPEA). These were boarding schools that were founded after the
Nazi's seizure of power in 1933.
Attendance and completion of the education qualified the students for higher education at the Reich's universities. Similar to the "Adolf-Hitler-Schools" and the SS' "Junkerschulen", the NPEAs were tasked with developing the future elite of Nazi Germany.
These schools' purpose was to "educate the students to National Socialists, strong in body and mind for the service to the people and the state".
This school was in fact the only NPEA to have been built especially for this purpose, all the others had been placed in existing schools and institutions - castles, hospitals and monasteries.
