A recent email enquiry from a reader prompted me to publish this post. I had researched it earlier, but when I received an email from "nemo" asking me to identify some curious structures that are scattered about the city, I decided to go ahead and post it.
Here is a photograph of these objects. What are they - can you guess? I'll give you their locations, from left to right:
1. St Pauls Terrace, Spring Hill - opposite Gloucester St
2. Florence St, Teneriffe - corner of Macquarie St, next to woolstore
3. Wickham Terrace, Spring Hill - opposite Twine St, outside Albert Park
The structures are all made from Monier reinforced concrete and were among the first uses of this product in Queensland. They were built around 1904.
OK, I'll put you out of your misery. These are ventilation shafts for Brisbane's stormwater drainage system. In the late 1870s and early 1880s, the Brisbane Municipal Council commenced to provide stormwater drains in the city, Spring Hill and Fortitude Valley areas. Brisbane's hilly terrain and tropical thunderstorms often created havoc for those living in low-lying areas (still happens, in fact), and so open drains were constructed to channel the water away to the river and creeks of the town. The drains were then covered in the 1890s.
However, Brisbane was not then sewered, and citizens and businesses had a tendency to dispose of household waste and refuse down the stormwater drains. This soon led to the creeks becoming fouled and the stormwater drains themselves blocked and smelly. An outbreak of bubonic plague in Brisbane around the year 1900 added to the concerns of citizens. In those days, it was thought that diseases could be transmitted by these odours, and so the Municipal Council allocated a sum of money to construct ventilation shafts for the drains as a health measure.
It is not known how many were erected, but these three shafts are all that are left.
