Eiffel Tower vs Two Prudential Plaza

Informations

The Eiffel Tower ( EYE-f?l; French: tour Eiffel [tu???f?l] (listen)) is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It's named after the engineer Gustave Eiffel, whose firm designed and built the tower. Constructed from 1887 to 1889 as the entrance to the 1889 World's Fair, it was initially criticised by a number of France's leading artists and intellectuals for its design, but it has become a worldwide cultural icon of France and one of the most recognisable structures on the planet. The Eiffel Tower is the most-visited paid monument in the world; 6.91 million people ascended it in 2015. The tower is 324 metres (1,063 ft) tall, about the same height as an 81-storey construction, and also the tallest structure in Paris. Its base is square, measuring 125 metres (410 ft) on each side. During its construction, the Eiffel Tower surpassed the Washington Monument to become the tallest man-made structure in the world, a title it held for 41 years until the Chrysler Building in New York City was completed in 1930.

It was the first structure to reach a height of 300 metres. Due to the addition of a broadcasting aerial at the top of the tower in 1957, it is now taller than the Chrysler Building by 5.2 metres (17 ft). Excluding transmitters, the Eiffel Tower is the second tallest freestanding construction in France after the Millau Viaduct. The tower has three levels for people, with restaurants on the first and second degrees. The top level's upper stage is 276 m (906 ft) above the floor -- the maximum observation deck available to the general public in the European Union. Tickets can be bought to ascend by lift or stairs to the first and second degrees. The climb from ground level to the first level is over 300 steps, as is the climb in the first level to the second. Although there is a staircase to the top level, it is usually available only by lift.

Two Prudential Plaza is a 64-story skyscraper located in the Loop area of Chicago, Illinois, United States.

At 995 ft (303 m) tall, it's now the sixth-tallest building in Chicago and the seventeenth-tallest in the U.S., being only five feet from 1,000 ft, making it the closest of any building under 1,000. Built in 1990, the building was designed by the firm Loebl Schlossman & Hackl, with Stephen T. Wright as the principal in charge of design. It has been honored with 8 awards, including winning the Best Structure Award from the Structural Engineers Association of Illinois in 1995. At the time of completion, Two Prudential was the world's tallest reinforced concrete building. Its distinctive shape features stacked chevron setbacks on the north and south sides, a pyramidal peak rotated 45°, and an 80-foot (24 m) spire. The building is attached to One Prudential Plaza (formerly called the Prudential Building). With no spire, the building's height is still slightly greater than that of One Prudential Plaza's pinnacle.In May 2006, BentleyForbes, a Los Angeles-based property investment firm, run by Frederick Wehba and his family bought Two Prudential Plaza, along with its sister property, One Prudential Plaza for $470 million.In 2015, BentleyForbes defaulted on the mortgage for the towers on account of the terrific Recession and New York-based investors 601W Firms and Berkley Properties took control of the property after investing more than $100 million in equity to recapitalize.
