Greensburg is a city in, and the county seat of, Kiowa County, Kansas, United States. As of the 2010 census, the city population was 777, and before the tornado, in 2000 the population was 1,544.
In the evening of May 4, 2007, Greensburg was devastated by an EF5 tornado that traveled rapidly through the area, leveling at least 95 percent of the city and killing eleven people between the ages of 46 and 84.
Greensburg today stands as a model "green town", often described as the greenest in America. The hospital, city hall, and school have all been built to the highest certification level issued by Leadership in Energy and Environmental Design (LEED). Greensburg is also home to the world's largest hand-dug well.
