The Harrison School  was located on the NE corner of Zediker (Road 24) and Kamm Avenues, 3 miles NE of Kingsburg. The Clay School building was the first building to be located in this Historical Park.

The Clay School building was closed to the public on 3/5/08 and subsequently emptied of all contents in preparation for a major renovation which began on 4/18/09; consisting of new trusses, roof, ceilings & the installation of a fire suppression sprinkler system. The plaster on the inside walls was removed & new dry-wall installed over the lath. The electrical re-wiring in the walls & ceiling with additional ceiling fans & outside lighting were installed. The light fixtures in the three large rooms arrived for duty circa 1950. The building was approximately 85% insulated & was repainted on the inside to original colors. The U.S. Flag was restored atop the bell tower after having been last seen there circa 1917. The tall flag pole nearest the Clay building served as the official flag pole for Clay Elementary School from 1916 – 1993. The restoration project was made possible by a financial grant from the Larry Hillblom Foundation and generous financial donations from two Clay School graduates, Helen Nord Wigh (1930) and Jack Martin (1940). The building was officially reopened to tourists on April 24, 2010.
