Apple Park is huge. According to Wikipedia the main building—called the Ring—has a circumference of one mile. And Wired reports it features a three-quarter mile walkway along the inner border.
The Ring also features the largest curved-glass panels in the world. In fact, over 3,000 glass panels form the four-story building. Each pane is almost 50 feet wide.
