When you visit France you can tour various royal homes, like the Palace of Versailles and they seem pretty intact. Were the homes of royalty and the rich not destroyed or looted during the revolution?
Not to detract from your question regarding royal property, but the French Revolution did see significant cultural destruction including the Cluny Abby which was one one of the wealthiest and most influential monasteries in Europe. While the Abby was no longer in its heyday by the time of the Revolution, its library and church were destroyed before the rest of the Abby was sold off.
