Indeed. The late King aready bequeathed a considerable sum for the creation of a monastery on the royal domain in Opgrimbie, near the Dutch border. The monastery (a modern complex consisting of 25 cloisters, every cloister inhabited by one Sister living in isolation when not in communio) is inhabited Sisters of Bethlehem, a very traditional Order living according the strictest rules.
I hope that Queen Fabiola has enough private funds to bequeath a sum to this project which was (is) dear to her late spouse and herself. Meaning that it is not needed to sell jewels for this. Fingers crossed that she will bequeath her jewels to the Duke of Brabant.
