One World Trade Center Quiz – Geometry and 1,776 Feet

One World Trade Center, opened in November 2014, is the tallest building in the Western Hemisphere. Its spire tops out at 1,776 feet, honoring the year of the Declaration of Independence.

Designed by David Childs of Skidmore, Owings and Merrill, it rises from a square base about 200 feet wide, matching the footprint of each original Twin Tower. Its edges are chamfered into eight tall isosceles triangles, forming an octagon at mid-height and a smaller square at the top.

The roof parapet stands at 1,368 feet, recalling the original towers, and a 408-foot spire carries antennas. The One World Observatory occupies floors 100 to 102. The building was once called the Freedom Tower.
