The structure which is now a museum is the 1942 addition to the original building. It is one of the few early twentieth-century wood frame schoolhouses still standing in Lee County. The original Williams Academy built-in 1912 was Lee County's first government-funded school for black (‘colored') students. The school was named after J. S. Williams, Supervisor of the Colored Schools. The Black students throughout Lee County and Punta Gorda attended school at the academy.
The building is divided into two rooms. One room displays historical memorabilia of local black citizens and the history and culture of the black community.The other room is an interactive classroom staged as a 1940's segregated southern classroom for ‘colored' students. It provided a visual contrast to the facilities provided to white students.
