Convict barn built in 1844. This large building was erected in 1844 as a store for agricultural produce from the nearby farm, about the site of the present airstrip. There are two features unusual in a convict building: it was not white-washed internally, and it boasts a triple diamond pattern high on the external wall facing the Cemetery. During the 1920s it became a machine repair and carpenter’s shop for the cement company’s railway system.
