The school was opened originally in 1892 as Lion Mill School. In 1954, it became Mount Helena Junior High School, serving both primary students and secondary students from years eight to ten. The original school consists of single storey, linear brick buildings with a clay tile roof. It is built in a non-specific architectural style, although it borrows elements from the California bungalow style and the Post War International Style. It was built between 1951 and 1960 in three stages.
