Green Hills is a neighborhood in Nashville, Tennessee. Green Hills is located south of downtown Nashville on Hillsboro Pike. Green Hills is one of Nashville's most affluent areas, often chosen by residents who do not wish a long commute to downtown businesses and three area universities – Vanderbilt, Belmont, and Lipscomb Universities. Green Hills is also the home to The Mall at Green Hills, a high-end enclosed shopping center which began as a "strip mall" in the early 1950s. Nordstrom and the Apple Store are some recent additions to the mall. Hillsboro Village, with its many interesting shops, is only three minutes away to the north. Early important businesses located nearby included the Green Hills Market, one of Nashville's first true supermarkets, and the Green Hills Theater, a cinema. The Bluebird Cafe, a famous live music venue, is located on Hillsboro Pike in Green Hills. Hillsboro High School, located directly across the highway from the Mall, actually predates much of the neighborhood, which began on a small scale in the 1930s but was not highly populated until after World War II. Another public educational institution is Julia Green Elementary School, a primary school. A major private educational institution is Lipscomb University and its associated elementary and high schools. Another is Harpeth Hall School, a prestigious girls' high school. Although there were some preliminary plans toward making it an incorporated town in the late 1950s and early 1960s, these plans were never completed. Green Hills is in many ways a typical development of its era. It is designed for automobile, not pedestrian, traffic and originally consisted primarily of brick-veneer "ranch" styledetached houses on large lots. In more recent years, there has been considerable "infill" as many of the larger lots and other remaining open spaces have been redivided to become the sites of higher-density developments. As Green Hills is neither an incorporated town nor a census-designated place, exact boundaries are disputable and hence an exact population impossible to calculate. However, a common definition of Green Hills is an area roughly bounded to the north by I-440, to the south by Harding Place, to the West by Estes Road, and to the East by Lealand Lane; this area is approximately coextensive with the northern half of United States Postal Service's ZIP code 37215, designated "Green Hills Station." It is, though, part of the Metropolitan Government of Nashville and Davidson County. Therefore, mailed items sent to residents of, and businesses in, Green Hills have "Nashville, TN" in the address, not "Green Hills, TN."
