Prior to 1912, the young children of Cortez were educated in a one-room, wood schoolhouse. In 1912, the one-room schoolhouse was replaced with a larger, brick schoolhouse referred to as the Cortez Rural Graded Schoolhouse. The Cortez Mother's Club played a large part in the construction and success of the new schoolhouse. This new schoolhouse became a community hub for Cortez, and provided shelter for many during the hurricane of 1921. The Cortez Rural Graded Schoolhouse was first build with three classrooms, but in 1933 one of the classrooms was extended to serve as an auditorium. This building was used as a school for the children of Cortez until 1961. An art school then leased the building before being sold to weaver Robert Sailors in 1974. Sailors used the schoolhouse as his home and studio. After his death, Manatee County purchased the schoolhouse and began the process of restoring it in 1999. In 2006, the schoolhouse was reopened as a museum. Today, the Cortez Rural Graded Schoolhouse houses the Florida Maritime Museum.
