Hello Jimbo and thank you for your question.

is buried at the Picpus Cemetery in Paris, France.

heroically led American Continental troops in the Battles of Monmouth
and Yorktown. When he was buried, dirt from Revolutionary War
battlefields was spread over his grave.”

“The Picpus Cemetery is buried deep in the twelfth arrondissement. It
was a peaceful convent with a large garden but was confiscated in the
name of the Republic and converted into a "House of Health and
Detention". The cemetery is the final burial place for many of the
slaughtered victims of the guillotine during the French Revolution.”
