THE State Register of Heritage Places has picked up an unusual new listing in Highgate’s landmark sewerage ventilation stack. Thankfully, the aroma of the Lincoln Street drawcard had long dissipated before Heritage Minister Michelle Roberts made a doorstop this week to talk up the architectural merits of the 38 metre structure, which opened in 1941 to ventilate Perth’s newly introduced reticulated sewerage system. "The Lincoln Street ventilation stack… is a significant example of an industrial structure designed in the Inter-War Art Deco style," Mrs Roberts said. Perth MLA John Hyde said the stack was a "fine piece of architecture" held with some affection by local residents. Apparently, the ventilation stack lasted just four weeks after opening, because of rapid corrosion of extractor fans from the production of hydrogen sulphide. Soon after its closure, the tower functioned as a hidden antenna for the WA Police Service’s wireless communications during World War II. The site continues to be leased to the WA Police Service.
