BOK Tower (formerly known as One Williams Center) is a skyscraper in downtown Tulsa, Oklahoma. At 203 m (667 ft) [2] in height, the 52-story tower was the tallest building in any of the five "Plains States": Oklahoma, Kansas, Nebraska, North Dakota, and South Dakota, as well as the surrounding states of Missouri, Arkansas and New Mexico, [3] until surpassed by Devon Tower in 2011. [4] It was built in 1976 and designed by Minoru Yamasaki & Associates, the same architect who designed the World Trade Center in New York City. This structure is very similar to the WTC towers in appearance and construction. [5]

Skyscraper tall building

A skyscraper is a continuously habitable high-rise building that has over 40 floors and is taller than approximately 150 m (492 ft). Historically, the term first referred to buildings with 10 to 20 floors in the 1880s. The definition shifted with advancing construction technology during the 20th century. Skyscrapers may host commercial offices or residential space, or both. For buildings above a height of 300 m (984 ft), the term "supertall" can be used, while skyscrapers reaching beyond 600 m (1,969 ft) are classified as "megatall".

Oklahoma State of the United States of America

Oklahoma is a state in the South Central region of the United States, bordered by Kansas on the north, Missouri on the northeast, Arkansas on the east, Texas on the south, New Mexico on the west, and Colorado on the northwest. It is the 20th-most extensive and the 28th-most populous of the fifty United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people". It is also known informally by its nickname, "The Sooner State", in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which dramatically increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were merged into the State of Oklahoma when it became the 46th state to enter the union on November 16, 1907. Its residents are known as Oklahomans, and its capital and largest city is Oklahoma City.



BOK Tower's lobby has marble walls and wall hangings which have a noted similarity to the decor in the former WTC. The similarities between the BOK Tower and the World Trade Center Towers are based upon the building's history. The tower was built for the Williams Companies; at the time of its construction, the CEO of Williams (John Williams) was impressed by the Twin Towers in New York. His original idea was to build four small-scale replicas of the towers in Tulsa. However, prior to the actual construction, he was informed of the inefficiencies that would be created from having 25-story towers on the small footprints he had in mind with the required elevators. The plan for a quarter scale replica was then changed to a single tower a quarter the footprint of a trade center tower but double the height of the four planned towers.[ citation needed ] The similarities have even led executives to rightfully joke that the architects just halved the plans for the tower.
