The current Kronos Museum - Piacenza Cathedral Complex was born in 2015 with the aim of documenting the history and life of the Cathedral and the Diocese. It is divided into three levels: the ground floor with the permanent exhibition, the second level dedicated to temporary exhibitions and a third dedicated to Code 65 and the archival section. From this level begins the ascent to the dome frescoed between 1626 and 1627 by Giovanni Francesco Barbieri known as Guercino. Only from January 2020 it is possible to admire closely the prophets David, Isaiah, Haggai, Hosea, Zechariah, Ezekiel, Micah, Jeremiah, the lunettes in which episodes from the childhood of Jesus alternate - Announcement to the Shepherds, Adoration of the shepherds, Presentation to the Temple and Flight into Egypt - and eight fascinating Sibyls. In the permanent collection there are precious altarpieces, such as The Ten Thousand Crucified Martyrs by Giovanni Andrea Sirani, the Madonna dello Zitto by Giovanni Battista Tagliasacchi, Death of San Francesco Saverio by Robert De Longe, San Gerolamo and the angel by Guido Reni in dialogue with an Achrome by Piero Manzoni.
