Do you know why a lighthouse looks the way it does????
It has to be tall to cast the light as far as possible.
The master had to be able to walk around on top to watch for boats in need of help, to polish the windows, to light the fire in the days before electricity.
In stormy nights, in rain and snow or fog there ceertainly were other things to think about than phallus.
The same with a church tower. It was to be seen for travellers, the bells had to hang high up to carry the sound as far as possible. The bells were not just for church service, but also to warn about fire or other danger.
