Vatican Museums

Accessible from the entrance hall after passing through the metal detector, the cloakroom is a free service made available by the Vatican Museums not only to make your visit more comfortable, but most of all to guarantee the safety of visitors, as well as the museum spaces and the entire artistic patrimony they house.
The desk for the collection of stored objects may be reached from the exit hall, at the foot of the Momo helical staircase.

For visitors with mobility problems, the Vatican Museums offer free wheelchair hire from the cloakroom (subject to availability). 
To hire a wheelchair, it is necessary to present a valid identity document and deposit.
