Samsung (Korea). Samsung C&T Cor­po­ra­tion (Con­struc­tion and Trade), es­tab­lished in 1938, is the origin of Samsung Group. Samsung C&T was the primary con­trac­tor of 3 worlds tallest skyscrap­er­s: Burj Khalifa, Petronas Twin Towers and Taipei 101.

Ju­ly-Au­gust. The tower stands 320 meters (1,050 ft) tall, about the same height as an 81-­s­torey build­ing. Because of thermal ex­pan­sion, the height varies by 15 cm (5.9 in) due to tem­per­a­ture.

For defense. The houses of Shibam are all made out of mud brick and rise 5 to 11 stories high, with each floor having one or two rooms. This ar­chi­tec­tural style was used in order to protect res­i­dents from Bedouin attacks. Shibam is listed as UNSECO World Heritage Site.

It was built quickly and under budget. The Empire State Building took only one year and 45 days to build, or 7 million man-hours. To this day, this is a record for a sky­scraper of its height. Due to reduced costs during the De­pres­sion, the final costs totaled only $24.7 million instead of the es­ti­mat­ed $43 million.

Empire State Building held the title for 42 years since 1931. It was sur­passed by the North Tower of the World Trade Center in 1972. An ear­ly-1970s proposal to dis­man­tle the spire and replace it with an ad­di­tion­al 11 floors, which would have made it once again the world's tallest at the time, was con­sid­ered but ul­ti­mate­ly re­ject­ed.

7. As no tra­di­tion­al or­ga­ni­za­tion or formal body awards or rec­og­nizes any rating over five-s­tar deluxe, such claims are mean­ing­less and pre­dom­i­nant­ly used for ad­ver­tis­ing pur­pos­es. The Burj Al Arab hotel says the label orig­i­nates from jour­nal­ists and that they neither en­cour­age its use nor do they use it in their ad­ver­tis­ing.

Tokyo Skytree (pic­tured) reached its full height of 634.0 meters (2,080 ft) in March 2011, making it the tallest tower in the world, dis­plac­ing the Canton Tower, and the second tallest struc­ture in the world.

Moscow. In 2012, seven of the fifteen tallest sky­scrapers in Europe were located in Moscow. There are also several high­-rise build­ings under con­struc­tion there.

Chicago school. The dis­tin­guish­ing features of the Chicago School are the use of steel-frame build­ings with masonry cladding, large plate-­glass window areas and limiting the amount of exterior or­na­men­ta­tion. Many Chicago School sky­scrapers contain the three parts of a clas­si­cal column.

Hong Kong lost its lead­er­ship to Dubai if only high­-rise sky­scrapers above 300m are counted. But in category "over 100m", its position is safe with over 2300 build­ings. It is followed by New York City with less than 800.
