The Puppet Castle was born from the collection of Giordano Ferrari, which is one of the most important collections of puppets and marionettes and related material. Inside the approximately three hundred square meters of the museum, a considerable part of what the Parma puppeteer has patiently collected in over sixty years of activity is exhibited. The collection is made up not only of pieces created by the Ferrari family, but above all of objects of different origins, collected, purchased or received as gifts from other artists. Further funds have been added to Giordano's already rich and precious collection, which includes around 1500 pieces including puppets, marionettes, heads and props, the first of which is that made up of the material collected by Franco Cristofori, donated to the Museum by his wife and by his children in the certainty of interpreting the will of the missing journalist.

The consistency of the collection is remarkable, it consists of over a thousand pieces including puppets, marionettes, props, volumes, manuscript scripts and theatrical scenarios. Added to these, 134 envelopes of documents, which offer the scholar a precious testimony of the world of puppetry. Another fund is that donated by the daughter of the Brescia engineer Amilcare Adamoli, an amateur puppeteer: it includes puppets, clothes, scripts, " special effects” (such as the pipe for the flames), backdrops and the complete theater that Adamoli himself had built. Then there are the television puppets of Gruppo 80, by Kitti Perria and Enrico Valenti, and the puppets of the painter Carlo Ludovico Bompiani (Rome 1902 – 1972) donated by his children Anna Vittoria and Giorgio, as well as all the material that constitutes the donations, smaller in quantity but certainly not for quality, received from artists, or from other bodies, or from scholars or simply from people who wanted to contribute to increasing this extraordinary heritage.
