A bit of context

One World Trade Center was designed not just to be the country’s tallest skyscraper, but also a symbol of resilience and remembrance following the destruction of the original Twin Towers. Its 1,776‑foot height was chosen very deliberately to echo 1776, the year the Declaration of Independence was signed, tying the building’s architecture directly to U.S. history.
