WORLD HISTORY

Detailed explanation-1: -The World Trade Center site, often referred to as “Ground Zero” or “the Pile” immediately after the September 11 attacks, is a 14.6-acre (5.9 ha) area in Lower Manhattan in New York City.

Detailed explanation-2: -One World Trade Center, also known as One World Trade, One WTC, and formerly the Freedom Tower (still sometimes used colloquially), is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City.

Detailed explanation-3: -The complex-located at the southwestern tip of Manhattan, near the shore of the Hudson River and a few blocks northwest of Wall Street-was built by the Port Authority of New York and New Jersey as a central facility for businesses and government agencies involved in international trade.

Detailed explanation-4: -When completed in 1973, 2 World Trade Center (the South Tower) became the second tallest building in the World – behind its twin, 1 World Trade Center. The South Tower’s rooftop observation deck was 1, 362 ft (415 m) high and its indoor observation deck was 1, 310 ft (400 m) high.

Detailed explanation-5: -Ground Zero-the site where the Twin Towers stood until two planes crashed into them on Sept. 11, 2001, sending them tumbling to the ground-looks quite different from how it did two decades ago, and it provides history, education, and a quiet place of reflection for tourists.
