20 years
The initial concept dates back to 1946 for a "World Trade Center" Development. There were numerous delays for a variety of reasons. However, demolition did not actually began until March 1966. The first tenants moved into the north tower in Dec 1970 with the first tenants moving into the south tower in Jan 1972. The ribbon cutting ceremony was in April 1973.
The first ideas about creating the world trade centers began in 1946, when the project was first proposed. However initial plans weren't released until 1961. At this point planning was halted, for the construction required approval from not only the eager governor of New York, but also the unwilling Governor of New Jersey. Finally in 1966 an agreement was made between the involved parties, the two governors, the mayor of New York, the New York City Council and the construction company the Port Authority Trans-Hudson (PATH). Shortly there after in 1966 groundbreaking of the construction began. For another four years construction on the two main towers continued, until on December 23 1970, the north tower's (Tower one) topping ceremony was held. The south tower's (tower two) topping ceremony was held nearly a year later on July 19, 1971. Finally the final ribbon cutting ceremony was held on April 4, 1973 at which point the towers were officially opened.
they were made in 1966 but it was in 1971 when both towers were complete so they lasted 35 years until they were destroyed by terrorists

It took approximately 2 years to build the Twin Towers.
until osama saw them
The Twin Towers were completed in 1972.
The Twin Towers were erected in the early 1970's with completion in 1972.
The foundations of the original Twin Towers have become memorial fountains, and a new tower (Freedom Tower) has been erected nearby to replace them.
The twin towers were never rebuilt or renamed. They are still simpily called the twin towers.

No there won't be. A monument site will be erected to remember the fallen. Apparently, somehow a Muslim community center was approved for the site. I believe this is very poor taste but others will disagree.
