Gasometers, love em or hate ’em they soon won’t be here anymore. Curiously when they were operational they were (imho) a bluddy eyesore. Once they were emptied and stripped to a bare skeletal form they developed an empathy within the area, and developed a personality favoured like so much of our beloved Victorian structures.
This didn’t preserve these huge structures, even if the remaining structure looked, well structural, the resulting hoarding remained an eyesore. But posterity still remembers these great structures even if they no longer remain in situ.
