Very pious, Clémentine was authorized by her parents to frequent Madame Cléry, the superior of the Collège du Sacré-Cœur de Jette, not far from Laeken. There she rubbed shoulders, for a few hours on Thursday and Sunday, with other aristocrats, such as Marguerite de Limburg-Stirum and Nathalie de Croÿ. In April 1889, two months after the death of her brother-in-law Rudolf in strange circumstances in Mayerling, Clémentine and her mother stayed with Stéphanie, now widowed, at the Miramare Castle. The two sisters strengthened their bond and happily played music together. It was also in the spring of this year that Clémentine discovered the charms of Venice.
