Near Turin, Italy, a private art collection with notable works spanning the 13th-to-20th centuries, and valued at $600 million, will radically transform a contemporary art museum, reports the New York Times.

In a statement, the Fondazione Francesco Federico Cerruti per l’Arte, Castello di Rivoli Museo d’Arte Contemporanea says it is the first contemporary art museum to incorporate such an encyclopedic historic art collection. An expansion called Cerruti Villa will open on January 2, 2019.

A private collection of immense quality was amassed since the 1950s by Francesco Federico Cerruti, a secretive and reserved bookbinder-entrepreneur and passionate collector who passed away in 2015 at the age of 93, according to the museum statement. It includes 300 works of sculpture and painting, ranging from the Middle Ages to today, plus approximately 200 rare and ancient books, and over 300 furnishings including carpets and desks by renowned cabinet makers. The collection features masterpieces by Sassetta, Bernardo Daddi and Pontormo, Renoir, Modigliani, Kandinsky, Klee, Boccioni, Balla and Magritte, Bacon, Burri, Warhol, De Dominicis and Paolini.
