Built Heritage
The Gardens contain some of Tasmania's most significant built heritage. These structures form the bare bones around which the Gardens have waxed and waned over the years.
Important structures include the Superintendent's cottage (now the Administration Office) closely followed by the Arthur Wall. This wall, of a design common in Britain, is hollow and capable of being heated to encourage the growth of fruit trees planted beside it. Nobody had done their homework on Tasmania's climate, so it was soon discovered that fruit trees did very well without any help, and the wall was never used in this way.
At the northern end of this wall stands another cottage, built in 1845 originally for the head gardener, but which has since been a porter's lodge, overseer's residence, tea rooms, board room and administration office. Shortly before that, another brick wall, the longest convict built structure in Australia, transected the landscape from north to south. This is the Eardley-Wilmot wall, which legend states was built to keep out a plague of grasshoppers. Another early structure was the Lily Pond, formed by damming a stream from the Domain, and initially used for irrigation. It was not until 1878 that the spectacular set of wrought iron gates made in the north of England were installed. The Conservatory was constructed in 1939.
Recent construction in the Gardens reflects the changing focus of botanic gardens worldwide, providing facilities for the delivery of education, interpretation, conservation and research programs.
