General Information

The University of Naples “Federico II”, the oldest and biggest of the five Universities in Naples, was founded in 1215.

One of the oldest “lay” University in the world.

The third biggest University in Italy (90 000 students).

The Engineering Faculty has about 13 000 students with almost all engineering branches and graduated about 1000 engineers each year.
