The Pentagon, a colossal five-sided fortress nestled just across the Potomac River from Washington D.C., stands as a globally recognized symbol of American military might. More than just a building, it represents the heart of US defense strategy, a hub of power that shapes global events and safeguards national security. This article explores the multifaceted story of the Pentagon, from its architectural marvel to its enduring legacy in world affairs.

Its five-sided structure, initially envisioned as a compromise to fit within a pre-existing pentagonal plot, proved remarkably efficient, minimizing walking distances and maximizing internal space. The building's sheer size—covering nearly 18 acres—is a testament to its vast operational scope.
