Coralville is a city in Johnson County, Iowa, United States. It is a suburb of Iowa City and part of the Iowa City Metropolitan Statistical Area. The population was 18,907 at the 2010 census.HistoryCoralville is the location of the Edgewater Park Site, a 3,800-year-old archaeological site along the Iowa River. Edgewater is the oldest site in Iowa with evidence of domesticated plant use.Coralville incorporated as a city in June first, 1857. The city's name comes from the fossils that are found in the limestone along the Iowa River. In 1864 Louis Agassiz, a Harvard University zoologist, gave a lecture at the nearby University of Iowa titled “The Coral Reefs of Iowa City”. During the lecture he presented local samples of fossilized Devonian period coral. The lecture was well received and helped raise public interest in the local fossils. In 1866, more corals were discovered at the site of a new mill, inspiring the citizens of the area to name the settlement "Coralville". The first mill at Coralville was built in 1844, and in the years that followed, a number of mills were powered by the Coralville mill dam along the Iowa River, but all of the mills had closed by 1900, except for a low-head hydroelectric plant that remained in operation until the mid 20th century.
