A room in the museum is specifically dedicated to the works of Luca Signorelli and his workshop, and emphasizes the bond between Signorelli and his hometown, and correspond to the artist's last years of work, from 1512 to 1523, the year of his death. Ten of the works bear the personal signature of Signorelli, the others are assumed to be from his workshop.

The large tempera on panel depiction of the Lamentation of Christ, which used to be in the church of S. Margaret of Cortona, was called "a rare form of art" by Giorgio Vasari. The predella, on which Girolamo Genga may have also worked displays scenes of the Passion such as of the Last Supper, Agony in the Garden, and the Flagellation of Christ.
