Vaucluse House is one of Sydney’s few 19th-century mansions still surrounded by its original gardens and wooded grounds. Colonial emancipist William Charles Wentworth bought the house in 1827, and over the next 5 decades, William and his wife Sarah developed Vaucluse into a large and picturesque estate. The grounds were extended and flourished to cover most of the present-day suburb of Vaucluse. In 1915 Vaucluse House became Australia’s first official house museum and continues to entice visitors to its lush and still secluded grounds. In 2015, Vaucluse House celebrated 100 years of being a museum.
