Torre Colpatria vs Aon Center

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.
