In the early 21st century, WEM encompassed a total of 5.3 million square feet (with 3.8 million being devoted to retail). It was the largest mall in the Western Hemisphere, had the world's largest indoor amusement park, the world's largest indoor lake and the world's largest parking area, which provided free parking for nearly 20,000 autos.

Thus far, three trademarks have been used to promote the mall. Here we see the latest logo, which debuted in 2013.
