Sharp's Ridge is a steep limestone ridge in Knoxville, Tennessee, north of the city's downtown. A 111-acre (45 ha) area of the 7-mile (11 km) ridge is maintained as Sharp's Ridge Memorial Park, a city park dedicated to the honor of the area's war dead. The ridge also is the site of a transmitting antenna farm that serves most of Knoxville's broadcasters. The highest ground point on the ridge is an abandoned fire tower located at 1,391 feet (424 m) above mean sea level.
