The tour starts at The Glass Dome at Wynyard Park. This small park is closely connected to the history of the city. and was made a public park in 1887. It was earlier a part of the Soldier’s Parade Ground and Barracks that was used by the guards of the many convicts that arrived in Sydney till 1840. The Dome Glass has an underground lavatory that was built in 1912. A small, pleasant place to start this evening walk.
