The Marini Foundation is situated in the 14th century Convent of Tau, dedicated to St. Anthony Abbot, and known as the Tau because of the blue enamel T that marked the cloaks of this religious order.

The Convent, which surrounds a small central cloister closed off by an inverted glass pyramid that allows rainwater to drain into an ancient well, is composed of several rooms containing a rich collection of Marino's works that testify to his artistic production. On several levels, the large and harmoniously arranged spaces ensure that the works on display can be fully enjoyed and thus permit a complete and comprehensive view of the subjects Marino covered over the years: his equestrian figures, his Pomonas, his portraits, and his acrobats and figures from the circus and theatre.

The Foundation archives boast a fine library that specialises publications on Marino's work, including monographs, catalogues, art magazines and a comprehensive collection of newspaper cuttings from 1927 to the present day. This bibliographic nucleus is complemented by another collection on art in general, especially modern and contemporary art. It also contains a photographic collection and slide and video libraries documenting the life and work of Marino Marini.

The Museum also functions as a multi-purpose space for interdisciplinary arts, hosting temporary exhibitions dedicated to other artists, photographic shows and cultural events, such as concerts, theatre performances, conferences, poetry readings and book presentations.

These activities help to keep the links with the city alive and ensure a continuous cultural enrichment, making it an important centre of aggregation.

The Foundation’s Scientific Commission also accepts requests for authentication of any work attributed to the Artist as part of its function in the promotion and protection of Marino Marini's work and memory. After viewing, the artwork undergoes a technical inspection to make sure that it really is part of the artist’s production; a certificate of authenticity is only issued when the answer is favourable and it can then be included in the Archive’s catalogue of signed works.

The Foundation’s Educational Department has been carrying out guided tours, workshops and routes since 2001, making use of various artistic languages – music, theatre and ballet – in order to place the visitor - adult or child - in the midst of a didactic and 'emotional' experience.

The guides make use of various different languages, adapting them to suit their listener’s receptive capacities, while also using the very latest educational methods to stimulate individual creativity and create memorable experiences.

The Foundation also contributes with inbound and outbound loans of Marino Marini's work to many exhibitions in Italy and abroad every year, ensuring an excellent level of security in the various stages of transportation and packaging. The Foundation's archives in fact contain records of all the loans and the various exhibitions in which it has taken part over the years.
