The Third Ward School was built in 1876 as a primary and intermediate grade  school and then became the city's first kindergarten. In 1918, it was converted to a "fresh air school", a new concept, providing education and nourishing meals for children with tuberculosis, until 1932. It then served as the headquarters for the city's health department for around forty years. The schoolhouse was designed by Arvin L. Weeks, a 19th-century Sheboygan architect. Altered at several points, restrooms were first installed in the north half of the foyer in 1904. Interior walls were added in 1931. It was placed on the National Register of Historic Places in 1981. In 1983 a  grant from the National Trust for Historic Preservation provided funds for a feasibility study to restore the building as a Sheboygan Area School District "living school museum".
