This Day in History: , One World Trade Center <br />Officially Opens in NYC.<br />November 3, 2014.<br />Construction for the tower <br />where the former Twin Towers <br />stood began in 2006.<br />Following the 9/11 terrorist <br />attacks, a competition was <br />held to find a lead architect <br />for a new structure.<br />Polish-American architect Daniel Libeskind won the competition. His vision of an asymmetrical tower wasn't realized, however.<br />Leaseholder Larry Silverstein employed his preferred architect, David Childs. Childs' design of a more traditional tower was also eventually changed.<br />Critics commented that the slow pace of construction allowed for a "sense of emblematic rebirth" to <br />become "more acute and irresistible.".<br />Today, tenants of One World Trade Center <br />include several major financial companies, <br />as well as media and tech companies
