What do the staff do on Mondays when the museum is closed to the public?

Curators, restorers, maintenance technicians, security, installers, etc. use the Mondays to work directly with the works or to adapt and check the installations, or if it is necessary to carry out any actions.  It is the most suitable day for having access to the works of art (both for studying them and for preventive conservation or photography), often with elevating machines or scaffolding. It is also a day for touching up the painting of the installations and in which, if necessary, works are transferred to the photographic set  to serve for internal requests or external images.  It is the day reserved for doing essential tasks in the rooms so as to be able to offer a good service on the other days of the week.
