Hardy had a difficult time finding a publisher for Tess of the D'Urbervilles because of all the sexy stuff. (Source: Dolin, Tim, ed. "A History of the Text."Tess of the D'Urbervilles: A Pure Womanby Thomas Hardy. London: Penguin, 1998.)
Even though the county of Wessex in which Tess of the D'Urbervilles takes place is a fictionalized version of a real area of England, many Hardy fans have tried to find the "real life" houses and valleys that inspired Hardy. This website has photos taken of some of the possible locations in Tess, including photos of Stonehenge.
