Greensboro is a city in the U.S. state of North Carolina. It is the third-largest city by population, in North Carolina and the largest city in Guilford County and the surrounding Piedmont Triad metropolitan region. Greensboro has grown to be part of a thriving metropolitan area called the Triad, which encompasses three major cities (Greensboro, High Point, and Winston-Salem) and more than a million people. Greensboro evolved from a small center of government to an early 1900s textile and transportation hub, and today is emerging as one of the South's up-and-coming centers for relocating businesses. Two centuries later Greensboro is still collecting accolades for its beauty and livability.
