Italy is mulling upping the cost of admission to its museums and galleries.
Ticket prices may rise in order to fund additional security and protection measures in cultural attractions.
The move comes after climate protesters threw flour over a Warhol-painted car in a Milan museum.
Italy’s culture ministry has said fears over damage to its artistic heritage means introducing a higher level of protection in museums and galleries is necessary.
“The continuous attacks and offenses that are increasingly occurring and damaging our artistic and cultural heritage require us to rethink and reinforce their level of protection,” the Minister of Culture, Gennaro Sangiuliano, said in a statement.
“[These attacks] lead us to take immediate measures, starting with covering all the paintings with glass.”
It is unclear whether these measures will be implemented in all museums in Italy, which would be a significant undertaking.
“Considering the enormous heritage to be protected, the intervention will represent a considerable cost for the ministry and of the entire nation,” added Sangiuliano.
“Unfortunately, I can only foresee an increase in the cost of the entrance ticket.”
Earlier this year, activists from the Ultima Generazione group glued themselves to the plinth of a sculpture in Milan’s Museo del Novecento. The artwork targeted was Unique Forms of Continuity in Space (1913) by notable Futurist artist Umberto Boccioni.
