BOK Center, Tulsa, US

The BOK Center, or Bank of Oklahoma Center, is a 19,199-seat multi-purpose arena and a primary indoor sports and event venue in Tulsa, Oklahoma. Designed to accommodate arena football, hockey, basketball, concerts, and similar events, the facility was built at a cost of $178 million in public funds and an additional $18 million in privately-funded upgrades. Ground was broken on August 31, 2005 and a ribbon cutting involving Tulsa musicians Garth Brooks and Hanson took place on August 30, 2008. The arena encompasses 565,000 square feet (52,500 m2) and reaches a maximum height of 134 feet (41 m). Inside, the bowl area's ceiling rests 120 feet (37 m) over the base floor and a 930-foot (280 m)-long HD ribbon screen wraps around the three-level seating area. There are 17,343 fixed seats, each ranging from 20 inches (510 mm) to 22 inches (560 mm) wide.
