The BOK Center is located in Tulsa, Oklahoma and many big events are held here. From concerts, sport games, and graduations, there is usually an event for everybody. It is the closest arena to my hometown, and also known for its circular structure. The designer was actually asked to create an architectural icon for Tulsa. When you first see it, you can see that almost half of the building is windows. There are staircases inside that follow the windows all the way up to the highest seats in the building. Almost 20,000 seats and each one makes you feel as if you’re right on stage. But I have noticed that if there is a stage that isn’t also circular, they close off the back half of the arena. So, artists who have designed a stage that isn’t round, they lose out in almost fourth of the ticket sales. I have been here many times for concerts, basketball games, and other events, and each time feels like a new experience. They obviously decorate the inside to coincide with the event, but the building itself always adds drama to your experience.
