This seems to be a long barrel misregistration. You might imagine this to be a long barrel cannon with external combustion for a 19th century attempt at a lunar landing module a la J.V. In practice it is central HVAC. (Heating, Ventilation, Air Conditioning). Spoke to one of the locals. "Fully reconditioned with all the latest scrubbers and cleaners, healthier than cigarette smoke really if you draw directly from the top of the stack". The last of the great long barrels. The smoking factory stack, a thing of the past here sorry to say.
