Corana and Hygeia are a heritage-listed pair of semi-detached residences at 211–215 Avoca Street in the Sydney suburb of Randwick, New South Wales, Australia.

[2] Pre-1780s the local Aboriginal people in the area used the site for fishing and cultural activities; rock engravings, grinding grooves and middens remain in evidence.

[5] By the mid nineteenth century the traditional owners of this land had typically either moved inland in search of food and shelter, or had died as the result of European disease or confrontation with British colonisers.

[4][2] One of the earliest land grants in this area was made in 1824 to Captain Francis Marsh, who received 4.9 hectares (12 acres) bounded by the present Botany and High Streets, Alison and Belmore Roads.

The village was isolated from Sydney by swamps and sandhills, and although a horse-bus was operated by a man named Grice from the late 1850s, the journey was more a test of nerves than a pleasure jaunt.

The wealthy lived elegantly in large houses built when Pearce promoted Randwick and Coogee as a fashionable area.

An even poorer group were the immigrants who existed on the periphery of Randwick in a place called Irishtown, in the area now known as The Spot, around the junction of St.Paul's Street and Perouse Road.

Many European migrants have made their homes in the area, along with students and workers at the nearby University of NSW and the Prince of Wales Hospital.

[2][6]: 218–9 The site of Corona and Hygeia is part of an original crown grant purchased in 1853 by Judge Callaghan, Chairman of the Court of Quarter Sessions, Sydney.

Judge Callaghan built and occupied Avoca which stood opposite Nugal Hall at 16-18 Milford Street Randwick.

[2] His widow, Elizabeth and his daughter Mary Milford Auber Jones, built the two large attached houses at 211-215 Avoca Street, Randwick apparently for rental.

[2] In January 1984, the Heritage Branch received representations from the National Trust of Australia (NSW) concerned at the deteriorated state and vacancy of the building.

[2][7] Corona and Hygeia are an attached pair of large semi-detached mansions designed in the late Victorian Italianate style.

[2] As at 19 September 2011, Corana and Hygeia are of State heritage significance as two semi-detached mansions in the late Victorian style and constructed in 1898.

They have particular aesthetic significance as a large and picturesque late Victorian two-storey pair of houses with good cast-iron work on the verandah valences and columns.

It has heavily decorated balustraded roof parapets, classically derived tiled verandah floors and front fences of cast iron and masonry.
