Princes of Studies
The portraits of the “Princes of Studies”, a title conferred annually on the most meritorious of those students who were terminating their scholastic career, hang along the wide corridors of the ground and first floors of the Carlo Alberto Royal College.
The more than 100 portraits, covering the period from1846 to 1972, constitute an important collection of over a century of Italian portrait painting.

Natural History Collections
The College's natural history collection is housed in glass cases along the walls of the first and second floor corridors. This collection played an important role in the teaching of Natural History at the College.
The collection is diversified in sections dedicated to zoology, mineralogy, paleontology, botany (numbering several interesting pieces preserved by Father Pellanda, a well-known botanist) and ethnograpy (including the armor of a Japanese Samurai), with a limited number of examples of entomology and comparative anatomy.
Among those who donated their private collections, particularly worthy of note are the Bonaparte family, and Umberto I and the Princess Clotilde of the Savoy family.

The Collection of Scientific Instrument
The collection of scientific instruments of the Collegio, although not widely known, is of great interest. It was composed in large part at the initiative of Father Francesco Denza, physicist and founder of Italian meteorology.
This collection, which is destined to be relocated to a more suitable location within the College, also includes a number of instruments that are part of the Meteorological Observatory, notable among them an anemojetograph, which registers on paper rainfall and the direction and speed of winds.
The 332 instruments making up this collection have all been catalogued and include many constructed by a Turin firm, that of the Jest family, one of the better known makers of scientific instruments during the 19 th century.
