In 1842, she commissioned a classical temple, and named it Ancanthe, 'blooming valley'. She intended the building to serve as a museum for Hobart, and left in trust to ensure the continuance of what she hoped would become the focus of the colony's cultural aspirations. A century of apathy followed, with the museum used as an apple shed among other functions; but in 1949 it was made the home of the Art Society of Tasmania, who rescued the building. It is now known as the Lady Franklin Gallery.
