Wivenhoe is a Mediterranean style villa situated on the Mater Dei property. It is close to both Cobbitty and Narellan and stands on a ridge overlooking Camden Valley and Camden Airport, with views to the Razorback Range. Wivenhoe is of both State and National Heritage significance and is the only extant example of a bell cast roof that was carved from a single beam. Some interiors are also available.
The Mater Dei property comprises some three hundred and eighty hectares adjoining the Nepean River. It contains substantial areas of natural bushland and, where possible, pasture has been established to undertake grazing of livestock, primarily cattle. The property was once a dairy, however this ceased to exist in the early 1960s although the old milking bail is still standing.
