..of Mary Whitehouse,
what filthy mind designed that lighthouse”
Mary Whitehouse was a firebrand protectress of public morals in Britain in the 1960s and 70s – Sisyphus springs to mind… – and the Heunensäule on the market square in Mainz never fails to remind of this 2 line rhyme.
You’ll be disappointed to know that it has absolutely no phallic symbolism.
Mainz DOES have one of those, though – the Drusus Stone in the Citadelle.
I’ve tried posting it a couple of times, but it doesn’t get past the Safe Search filter….
