The Washington Monument is an obelisk on the National Mall in Washington, D.C., Constructed to commemorate George Washington, once commander-in-chief of the Continental Army (1775--1784) in the American Revolutionary War and the first President of the United States (1789--1797).
Located almost due east of the Reflecting Pool and the Lincoln Memorial, the monument, made of marble, granite, and bluestone gneiss, is both the world's tallest predominantly stone structure and the world's tallest obelisk, standing 554 ft 7 11?32 inches (169.046 m) tall according to the U.S. National Geodetic Survey (measured 2013--14) or 555 ft 5 1?8 inches (169.294 m) tall according to the National Park Service (measured 1884). It's the tallest monumental column in the world if all are measured above their pedestrian entrances. Overtaking the Cologne Cathedral, it was the tallest structure in the world between 1884 and 1889, and it had been overtaken by the Eiffel Tower in Paris. Construction of the monument began in 1848 and was stopped for a period of 23 years, from 1854 to 1877 because of a lack of capital, a battle for control within the Washington National Monument Society, and the American Civil War. Although the stone structure was completed in 1884, inner ironwork, the knoll, and installation of memorial stones weren't completed until 1888. A difference in shading of the marble, visible approximately 150 ft (46 m) or 27% up, shows where construction was halted and later resumed with marble from a different source. The original design was by Robert Mills (1781--1855) of South Carolina, but he did not include his proposed colonnade because of a lack of funds, proceeding only with a bare obelisk. The cornerstone was laid on July 4, 1848; the first stone was set atop the unfinished stump on August 7, 1880; the capstone was set on December 6, 1884; the completed monument was dedicated on February 21, 1885; and officially opened October 9, 1888. The Washington Monument is a hollow Egyptian style stone obelisk with a 500-foot (152.4 m) tall column surmounted by a 55-foot (16.8 m) tall pyramidion. Its walls are 15 feet (4.6 m) thick at its base and 1 1?2 ft (0.46 m) thick at their top. The marble pyramidion has thin walls only 7 inches (18 cm) thick supported by six arches, two between opposite walls which cross at the center of the pyramidion and four smaller corner arches.Prime Tower | |

The Prime Tower, also called'Maag-Tower' in a previous stage of preparation, is a skyscraper in Zurich, Switzerland. At a height of 126 metres (413 feet ), it was the highest skyscraper in Switzerland from 2011 until 2015, when the Roche Tower at Basel (standing at 178 metres (584 feet )) was finished. The building is situated near the Hardbrücke railway station. The tower replaces an industrial facility that's been demolished. According to its developers, the tower's construction, which took 15 years to plan and execute, was a financial success, with its valuation based on rental rates exceeding the building cost by CHF 110 million.The tower and its two companion buildings, Cubus and Diagonal, are used primarily as office buildings. Due to its opening in December 2011, the tower hosts the'Clouds' restaurant on its top floor, a conference center, the Hotel Rivington & Sons on the ground floor, in addition to the offices of Deutsche Bank Schweiz, Homburger AG, Transammonia, Korn/Ferry International, Citibank Switzerland, Infosys, Repower AG, Ernst & Young, Zürcher Kantonalbank and consulting firms.
