One World Trade Center rose as the rebuilt main tower of the World Trade Center complex in Lower Manhattan after delays caused by disputes over money, security, and design. Following resolution of those conflicts in 2006, construction advanced from foundation work to a steadily rising steel and concrete structure, reaching street level in 2008, passing 600 feet by the end of 2010, and attaining roof level and structural completion in 2012. A colonial-era sailing ship uncovered during excavation connected the site to Manhattan’s earlier waterfront history. In 2013 the completed spire made the tower the tallest building in the Western Hemisphere, and it opened in 2014, with its observatory following in 2015.
