Built in 1816, this building with over 200 years of history is the oldest standing house in Sydney. It used to serve as coxswain, headquarters for the water police and then as a sailor's home.
It bears the name of John Cadman, who has been confined in Australia for the crime of stealing a horse. He lived here for 18 years and worked as the Superintendent of Boats.
In the past, the building used to be mere 2.5 metres away from the sea during high tide. Since then, the shore has moved by about 100 metres.
Overall, it's a good attraction to see if you're within proximity. The cottage cannot be visited and it can only be viewed from the outside. It's near the Circular Quay, Alfred St, Stand A bus stop, lines 301-303, 373, 374, 377, 500, 507, 515, 518, and 520.
Free guided tours of the grounds and bottom level of the house are available. They run on the 1st and 3rd Sunday of each month from 9.45am to 10.15am, excluding public holidays.
