Moroni Fort was erected in 1865 on the order of General D.H. Wells to protect settlers during the Black Hawk War. The fort covered the present City Hall Block and extended westward, with 12-foot rock walls supporting cabins along the inside. The bastion stood on the Lincoln School Lots, and its 3 by 16-foot walls held port holes that gave a view of the entire valley. In 1866, when nearby settlers were ordered to move into the fort, Fountain Green occupied the northeast section, Wales the west side, and Moroni the remainder.
