These things make me incredibly sad

From "The Art Newspaper" "Environmental activists defaced the Louvre pyramid on 27 October, covering the landmark glass monument with orange paint. Protestors from the Dernière Rénovation group threw balloons at the famous glass structure while one of the demonstrators climbed up the edge of the pyramid; according to the Telegraph, a dozen people were arrested following the incident. A Louvre spokesperson confirmed to The Art Newspaper that the activists attempted to cover the pyramid, the museum’s main entrance, with an orange liquid. “One of them climbed onto the pyramid's outer glass roof using climbing equipment. The liquid was sprayed onto the glass; traces are visible on the [structure]. No damage to the pyramid has been reported at this stage. Visitor access to the museum was maintained throughout the operation,” the spokesperson adds."
