1. Sphere
Upon opening, Sphere became one of the most recognizable buildings in the world. The exoskeleton of the massive orb (366 feet tall and 516 feet wide) lights up with LED displays ranging from yellow face emojis and a giant eyeball to a Halloween jack-o-lantern and even a snow globe. It's equally impressive inside as a concert venue, immersing concertgoers into the show. U2 opened Sphere with Phish and Dead and Company scheduled as its subsequent residencies. A 50-minute show called Postcard from Earth is also worth a visit.
