The current Kronos museum - Complex Piacenza Cathedral was founded in 2015 with the intent to document the history and life of the Cathedral and 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 the 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 since January 2020 you can see up close the prophets David, Isaiah, Haggai, Hosea, Zechariah, Ezekiel, Micah, Jeremiah, the lunettes of alternating episodes from Jesus - Annunciation to the Shepherds, Adoration of the Shepherds, Presentation to Temple and Flight into Egypt - and eight fascinating Sibille. In the permanent collection there are precious altarpieces, like the ten thousand martyrs crucified by Giovanni Andrea Sirani, Our Lady of Hush of John the Baptist Tagliasacchi, Death of St. Francis Xavier Robert De Longe, Saint Jerome and the Angel by Guido Reni in dialogue with a Achrome of Piero Manzoni.
