I've often heard that the Palace of Versailles was built with fewer bathrooms than it should have, which lead people to relieve themselves in corners or less congested rooms. I've also heard that women would just "go to the bathroom" as they walked, hoping the big skirts of their dresses would hide it, and have a servant behind cleaning up. In turn, this made the Palace a dirty and smelly place, which had to be emptied out twice a year for cleaning.
Is there any veracity to this or was it just a myth? How was hygiene in general treated back in 18th century France's most luxurious court?
