World Museum Day: World's largest museum

On World Museum Day, it's worth mentioning that the largest museum in the world by exhibition space is the New Century Global Center in Chengdu, China. While it is primarily known as a mixed-use building, it houses the New Century Global Center Exhibition Hall, which spans approximately 1.7 million square meters (18.3 million square feet). This vast exhibition space includes various displays, exhibits, and cultural showcases. It's important to note that the New Century Global Center primarily serves as a commercial complex, and its status as a museum is somewhat unconventional. When considering museums with a more traditional focus, the Louvre Museum in Paris remains one of the most significant and renowned institutions worldwide.
