Old King's School, Parramatta, Heritage school building near Parramatta River, Australia

Old King's School is a complex spanning multiple heritage buildings along O'Connell Street, featuring two-story structures in distinctive colonial style and riverside gardens. The site now houses Bayanami Public School while preserving several original 19th-century structures.

The site began as part of Mount Betham, a 42-hectare grant made to William Bligh in 1806. In the 1820s it passed to the Agricultural and Horticultural Society, which cleared and fenced the land and built a nursery. The society handed the property to The King's School's first master on 2 January 1834, and the school opened under Archdeacon William Broughton's plan for Anglican education.

The site's name comes from Archdeacon William Broughton, a former pupil of The King's School in Canterbury, England, who proposed "King's Schools" for the colony. His plan placed day boys in Sydney and boarders and day boys at Parramatta, teaching a classical, scientific and religious education to sons of middle and higher ranks, with Anglican instruction but no religious tests.

The buildings can be viewed from O'Connell Street near Parramatta River and are accessible for external viewing. Since the site operates as an active school, check access beforehand or visit during public tour days to explore the grounds properly.

The site was part of Mount Betham, a 42-hectare grant made to William Bligh by Governor King in 1806 for a private residence; Macquarie declared it null and void in 1819. Before the school, the Agricultural and Horticultural Society used the land as a nursery, selling its trees and plants in 1832.
