Next to the old kind of school, the Scholae Palatinae, established by Constantine the Great as a replacement to the Praetorian Guard, was the training center of the imperial palace guard.
The Motto of the school is seen on the facade above the main entrance and says "non scholae sed vitae discimus", in English "we learn, not for school, but for life", in its well-known inversion of the saying of Seneca "non vitae sed scholae discimus".
