ART

A gleaming and renovated Louvre museum, which has been undergoing a six-year, $850-million overhaul, will open this week in Paris. Visitors will find a new glass pyramid at the entrance, and high-tech, ultra-modern facilities inside. Video screens indicate in several languages which galleries are closed as well as the best routes for finding key works of art such as the Mona Lisa and Winged Victory. With about 650,000 square feet of additional space, dozens of important works have been dusted off and put on display for the first time in decades. When the last of its 14 new galleries opens in 1993, the Louvre is expected to be the world’s largest museum. The new pyramid entrance will be opened with flourish on Wednesday by President Francois Mitterrand.
