Sydney's Lost 3.6km Convict Tunnel | This Blew My Mind 😱

Sydney's Lost 3.6km Convict Tunnel was super interesting. I had no idea there was a massive convict-built tunnel running under Sydney. The history, the engineering, and how it stayed lost for so long really blew my mind. Learning about the conditions the convicts worked in and what this tunnel was used for gave me a whole new perspective on early Australian history. As an American, this is one of the coolest hidden gems I’ve discovered about Sydney.
