Hornby Lighthouse is a distinctively red-and-white vertically striped lighthouse located at the tip of South Head in Sydney Harbour. Designed by colonial architect Alexander Dawson and completed in 1858, it serves as the third oldest lighthouse in New South Wales. The structure was built to improve safety at the harbour entrance following two major shipwrecks, the Dunbar and the Catherine Adamson, in 1857. It stands 9 meters tall and is constructed from sandstone. The site offers a vantage point overlooking the Pacific Ocean and the entrance to Port Jackson. It is managed by the National Parks and Wildlife Service as part of the Sydney Harbour National Park. The lighthouse operates on a solar-powered LED system.
