It was closed from 13 January for extraordinary maintenance.
The museum houses the sinopias, that is to say the preparatory drawings for the vast frescoes that adorned the walls of the Camposanto. Here you can admire and compare the most extensive cycle of fourteenth-fifteenth-century graphics known to us.
In addition to the sinopias, the museum collects the engravings of Carlo Lasinio (1759-1838) the only complete documentation of what the murals of the Camposanto were once.
