Torre Colpatria vs Pentagon

Informations

The Torre Colpatria (English: Colpatria tower) is a 50-story skyscraper in the downtown area of Bogotá, Colombia. It's the third largest building in the nation and the fifth-tallest in South America. Constructed from 1973 to 1978 and opened in 1979, it has a complete height of 196 metres (643 ft), becoming the tallest skyscraper of Colombia and holding this title until 2016, when the south tower of the BD Bacatá was topped off. The main headquarters of the Colpatria Bank are located in the building, in addition to a large number of other banks and financial corporations have offices in it. The building lies at the intersection of 26th street and 7th avenue, in the heart of the city's downtown.

Since 1998 the Colpatria Tower was illuminated nightly with thirty-six color changing Xenon lights. But, in 2012, the Dutch lighting company Philips replaced the old lights with a 120-meters-high LED system to enhance the lighting of the construction and project high-definition pictures. . Due to that, and also because it was the tallest skyscraper in Colombia for almost 40 years, the building is a landmark in the nation and dominates Bogota's skyline along with other structures like the BD Bacatá, the World Trade Center, FONADE and Colseguros buildings.

The Pentagon is the headquarters building of the United States Department of Defense.

As a symbol of the U.S. military, the phrase The Pentagon is also often used as a metonym for the Department of Defense and its leadership. Located in Arlington County, Virginia, across the Potomac River from Washington, D.C., the building was designed by American architect George Bergstrom and constructed by contractor John McShain. Ground was broken on 11 September 1941, and the building was dedicated on 15 January 1943. General Brehon Somervell supplied the important motivating power behind the project; Colonel Leslie Groves was responsible for overseeing the project for the U.S. Army. The Pentagon is the world's largest office building, with about 6,500,000 sq feet (600,000 m2) of space, of which 3,700,000 sq feet (340,000 m2) are used as offices. Some 23,000 military and civilian employees, and another 3,000 non-defense support employees, work in the Pentagon. It has five sides, five floors above ground, two basement levels, and five ring corridors per floor with a total of 17.5 mi (28.2 km) of corridors. The fundamental five-acre (20,000 m2) pentagonal plaza is nicknamed'ground zero' on the presumption that it would be a prime target in a nuclear war.On 11 September 2001, exactly 60 years after the building's construction began, American Airlines Flight 77 was hijacked and flown into the western side of the building, killing 189 people (59 victims and the five terrorists on board the airliner, as well as 125 victims in the building), according to the 9/11 Commission Report. It was the first major foreign attack on Washington's governmental facilities since the town was burned by the British during the War of 1812. The Pentagon is listed on the National Register of Historic Places and is a National Historic Landmark.
