China just cut the ribbon on the world’s new largest building.

The New Century Global Center, which recently opened in Chendgu, China, is 328 feet high, 1,640 feet long, and 1,312 feet wide. That’s roughly 20 times the size of Sydney’s legendary Opera House, four times the size of Vatican City, and three times the size of the Pentagon. And its 420 acres in floor space is nearly the size of the entire country of Monaco (499 acres).

It’s an absolutely mammoth structure.

But what good would the world’s largest building be without a mind-boggling array of businesses, range of activities, and mix of amenities. Here are some of them.
