PARIS, Feb 13 (Reuters) - The Louvre museum's Denon gallery, where its most valuable paintings are displayed, was hit by a water leak on Thursday evening, though the area of the famous Da Vinci's Mona Lisa was unaffected, a union representative told Reuters on Friday.
"Due to a technical failure on the upper floor during the night, the area is closed to the public and a scaffolding has been set up," the representative said.
