La Châtre
Beaujon died in Paris in late 1786 of a hemiplegia (semiparalysis probably brought on by a stroke) and was honoured with a huge funeral pomp culminating with the deposition of his remains in a magnificent tomb in the chapel of St. Nicholas of Roule, which had been founded by him and built by his architect Girardin. Unfortunately, during the upheavals of the French Revolution, his tomb was desecrated, and Beaujon's ashes were strewn to the four winds. His immense fortune was left to his wife's niece Charlotte Bontemps Duchess de La Châtre and Marchioness de Jaucourt of whom descendants exist today (though they are of course not descendants of Beaujon himself).
