The visitor was visiting the world-famous museum on Saturday when he accidentally damaged a portrait of Tuscan prince Ferdinando de’ Medici, which was painted some time around 1695-1700 by Anton Domenico Gabbiani, the museum said on Monday.

The visitor, who hasn’t been publicly identified, was reported to the authorities. Meanwhile, the painting was removed from the exhibition for repair works, although the museum said the damage was “light” and it will be displayed again soon.

The incident prompted Simone Verde, director of the Uffizi Galleries, to issue a statement condemning “the problem of visitors who come to museums to make memes or take selfies for social media.”

“We will set very precise limits, preventing behaviours that are not compatible with the sense of our institutions and respect for cultural heritage,” he added in a statement sent to CNN.

Museum-goers accidentally damaging exhibits in the pursuit of the perfect photo appears to be an increasing problem for the institutions.

In April, a child damaged a huge painting by Mark Rothko, thought to be worth tens of millions of dollars, while visiting a Dutch museum.
