Here is a post about the Temple of Love, commissioned by Marie-Antoinette in the gardens of the Petit Trianon. There is a theory that it was built to celebrate the love of the king and the queen for each other and the consummation of their marriage, delayed for many years.
With all the discussions of unhappy and unfaithful royal marriages, there ought to be a book on the successful and devoted ones. Although many might disagree with me, I think Louis XVI and Marie-Antoinette ought to be profiled in such a study. More HERE.
