The Collectionnite Gallery displays odd collectibles, from early Wunderkammers to contemporary collections, as well as studies on collecting habits and psychology. We use the term collectionnite, which in French refers to collectomania with the suffixe "-ite" specifically referring to the concept of desease. In The Tricottet Collection, its use is made less pathological with collectionnite becoming an object that sounds just like a marcassite, an ammonite or a meteorite. For our work on the curating aspects of metacollecting and on the concept of collection-object, see Mignan (2016).

The Forteana Gallery displays objects, especially documents, related to fortean phenomena. The three sections are parapsychology (on spiritualism so far), cryptozoology (Loch ness monster, Mothman, the "Kubuyuruk") and ufology (UFO sightings, strange rains, alien monuments). This gallery is still in construction.

The Scientifica Gallery displays objects and documents relating to both fundamental and natural sciences, as well as to medicine. So far, sections include geometry, extraterrestrial life, phrenology and alienism. This gallery is still in construction.
