Roseneath Cottage, Heritage-listed cottage in Parramatta, Australia

Roseneath Cottage is a single-storey brick building at 40–42 O'Connell Street, Parramatta. Its wide panelled front door has a fanlight under a brick arch, flanked by two large shuttered windows with patterned brickwork above. A sandstone-paved verandah is supported by decorative timber posts.

It was built between 1835 and 1837 for Janet Templeton, a Scottish widow who became influential in Australia's wool trade. The building later passed through the hands of religious institutions that used it for schooling purposes.

The name Parramatta comes from Burramatta, meaning eel creek in the Darug language of the Burramatta people, the area's traditional owners. Janet Templeton's third daughter Marion married her cousin William Forlonge at the cottage in 1837. The building later served as a school.

The cottage is easily accessible from O'Connell Street and sits in a well-traveled area next to a school campus. You can view the building from the street and explore the surrounding Parramatta Park on foot.

The cottage was already standing in 1837, when Janet Templeton's third daughter Marion married her cousin William Forlonge there. The 1837 description notes a wide panelled front door with a fanlight under a brick arch, flanked by two large shuttered windows with patterned brickwork above.
