In 1978 a private group purchased much of the castle and the entire neoclassical gardens. The initial investments were focused on the recovery of the areas that best valorized the monument and allowed it to be opened to the public.
To facilitate the project, in 1985 a convention was drawn up between the owners and the cultural association Centro d’Arte e Cultura Castello di Belgioioso. In March 1992, the Prefecture of Pavia issued the final certificate of authorization for public entertainment.
Within a few years, having recognized the national value of various cultural initiatives organized at the castle, the association, supported by the Region of Lombardy in concert with the Province of Pavia, created the Ente Fiera dei Castelli di Belgioioso e Sartirana.
The Ente Fiera now boasts thirty years of experience in the organization of exhibitions and art events, drawing in more than 600 exhibitors and over 80,000 visitors each year.
