Hearing that somewhere there&#x27;s a tax on how many windows a housing has, I was confused and immediately rushed to search more about this weirdness.<p>Don&#x27;t know about correctness, but <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Window_tax" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Window_tax</a> says France got this until 1926, so it must be somewhat before the age of modern omnipresent advertising.
