The Gasworks Bridge carries Macarthur Street over the Parramatta River in the western suburb of Parramatta. This iron lattice bridge on sandstone pylons was completed in 1885 and acquired the name due to the proximity of the gasworks that once occupied the block southeast of the bridge. The south side of the bridge was the site of Howell’s wind and watermill, built in 1828 and used until 1868.
This contemporary artwork is located on the Parramatta River foreshore, near the Gasworks Bridge, in the western suburb of Parramatta. “Sentry Box” was created by historian Michael Flynn with artists Susan Milne and Greg Stonehouse in 2009. This 8-metre high sculpture is a reinterpretation of a small wooden sentry box which stood near this location, in the early days of the colony. The red coat soldiers were stationed on the river at the entry to Parramatta where they watched over the river and were responsible for keeping order and disciplining convicts.
