Durante Alberti's Trinity (circa 1538-1613) is an oil on canvas (373 x 192.5 cm) The work depicts the Trinity and the saints Andrew the Apostle, Mary Magdalene and Christina. The large altarpiece was created for the chapel of the Artini, or Aretini, family and is remembered in pastoral visits since 1582.

It was alienated from the cathedral in 1859 in a reorganization of the church which involved the elimination of 13 altars. It then entered the collection of the Lilloni Alberti family. Due to its large size, the canvas was divided into two fragments. The two fragments were purchased at an auction in 2002 and correctly restored and reunited by the current owners. With the donation, the owners intend to compensate the church for a serious loss suffered in the past, and also remember their respective parents, Veria and Franco Botticelli, and Alfredo Moretti. The donation is intended to be a significant gesture of affection of our families towards the cultural heritage of our country.
