Round House (The), Perth

This attraction, Western Australia's oldest public building, was completed in 1831. The Round House was used as a jail and a signal house. The limestone structure is very simple but the location stunning. Sitting on a high spot at the edge of the Indian Ocean, the site provides a fantastic view. You can look back down the Swan River to the city of Perth or out towards Rottnest Island . The gunnery tradition continues each day at 1pm when a visitor, selected from the crowd, fires the cannon.
