 Hadspen has buildings that are largely intact from colonial times, some of which date from the early parts of the 19th century. The Red Feather inn, an adjacent convict era gaol and four cottages form a cluster of heritage buildings in the midst of the town. The gaol is a sandstone structure that was used to overnight convicts. The inn, gaol and watchmans's cottage, St Andrew's church and Entally House are all listed on the Tasmanian Heritage Register, a recognition of their "historic cultural heritage significance to the whole of Tasmania".
