In response to the decision to construct a causeway across the River Derwent the Bridgewater Convict Station was established in 1828 on Ebenezer Geiss' grant at Black Snake. The station was west of the quarry on the southern side of the Causeway. Wooden barracks were constructed to accommodate the convict labour force (chain gang).
The station was decommissioned between 1847 and 1849. In 1847 the convicts were reputedly removed to Jericho in the Midlands. The station was still reported as open in 1849, possibly supplying some labour for the construction of a rolling bridge across the Derwent channel although by 1850 the station was no longer recorded as open. An 1886 plan shows that the site consisted largely of "traces of buildings".
The quarry face is clearly visible for approximately 300 m in the Granton Reserve.
A huge thank you to Netta & Mark Datlen, owners of the “Commandants Cottage” who graciously allowed me to take the photographs of their home.
