 It is Australia's first "House Museum", an important example of rare and forward thinking, public "preservation" and recreational planning of the early 20th century.With its family provenanced collection it demonstrates the way of life of the Wentworths, their taste incorporated with the taste of their time, social standing and status.The property, but particularly the house, reflects a statement of where the Wentworths aspired to be, as opposed to where they were placed because of their family history (perception of Sarah and William Charles Wentworth's family convict origins by Sydney society).
