The Opera del Duomo and the Museum of Mercy can be visited using the only ticket

Director of the Museum of the Opera del Duomo Luca Bagnoli announced the signing of an agreement between the two most important city museums, which will have been valid for a year.

The ticket will cost 16 euros and will be valid for 72 hours from the first entry into one of the two museums.

The Museum of Mercy was reopened to the public after three years of restoration work in January 2016.
Since 2000, after years of closure, it was possible to visit it only by appointment.
