The collection of paintings of the Cassa di Risparmio di Tortona, acquired by the Foundation in 1999, was the first nucleus and at the same time represented the constitutive moment of what would later become the pinacoteca "il Divisionismo", a result obtained with the intervening in these years of a careful and targeted acquisition policy aimed at the realization of an ambitious cultural and museum project. The art gallery in its architectural elements, as we see it today, was inaugurated in September 2008. The exhibition complex has a total area of ​​over 600 square meters, is arranged on two levels, structured and furnished in accordance with the strict regulations of the law and to international museum standards, subject to attention and continuous technological updates aimed at the safety of the materials and works of art contained therein, it aims to offer our visitors the best museum experience.
Over 110 works exhibited by 50 artists. The Pinacoteca is the only museum project entirely dedicated to Divisionism, which is examined through works selected from among those that contributed to the artistic events of the period or played a role in its history.
 
Among the most significant Divisionist artists present, the figure of Giuseppe Pellizza da Volpedo stands out, who made the parable of life in a close relationship with the territory in which his art matured. The core of his works - over 20 paintings - is the largest by extension in a collection for public use.
