About This Place
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 15,123 at the 2000 census; a special census taken by the city in 2003 counted 17,269 residents, and the United States Census Bureau estimated that 18,250 people lived there in 2007.
Coralville 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 1873. The city's name comes from the fossils that are found in the limestone along the Iowa River. In 1866 Louis Agassiz, a Harvard University zoologist, gave a lecture at the nearby University of Iowa titled âThe Coral Reefs of Iowa Cityâ. During the lecture he presented local samples of fossilized Devonian era coral. This inspired 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.
