Iandra Castle, Heritage-listed homestead in Greenethorpe, Australia

Iandra Castle is a homestead in Greenethorpe, New South Wales, built in the Federation style with Romanesque Revival details and constructed from steel-reinforced concrete. The building has dozens of rooms spread across a large rural estate listed on the New South Wales State Heritage Register.

A brick house was first built on the land in 1880, before George Greene directed the construction of the current building, which was completed in 1910. The change from a modest dwelling to a large castle-like structure shows how the region's farming fortunes grew over those decades.

The property became a center for progressive agricultural ideas in the region, attracting visitors interested in its innovative farming methods and philosophies. The buildings and gardens reflect the prosperity and forward-thinking approach of those who developed it.

Iandra Castle stands 11 kilometres south of Greenethorpe, in the Central West region of New South Wales. The homestead is a former Methodist boys' home and working farmland, so visitors should check opening arrangements before travelling. The grounds and outbuildings are spread over a large rural estate, and comfortable shoes are useful for walking between them.

The homestead's small Gothic stone church and extensive outbuildings made it a showpiece that attracted flocks of visitors before 1900. George Greene also pioneered share-farming at Iandra in 1892, supplying land and seed while share farmers provided labour; by 1911 fifty share farmers worked 7,300 hectares.
