Located in Cowell’s Old Post Office and Post Master’s residence dating from about 1888, the museum features a comprehensive display of photos, documents, books, household and agricultural items, local geological specimens, local shells and aboriginal artefacts, telling the history and development of the Franklin Harbour Area. Three rooms – a kitchen, living room and bedroom – have been arranged in the period of the late 19th century. The building was originally restored by the National Trust.
The group managing the museum also look after the Agricultural Museum situated on the Lincoln Highway featuring a fully restored 1910 Ruston Proctor Steam traction engine.
