“precious volumes were mostly dispersed after his death, a number of them found their way early on into the Bibliothèque nationale. Indeed, they may fairly be seen as the foundational tomes of the national library of France. In 1986, after preliminary excavations had been carried out for the Grand Louvre of François Mitterrand, one of the stones from the tower of Charles’s library came to light. In an extraordinary act of symbolism, it was taken across the Seine to the Left Bank, where it now forms the cornerstone of the new national library, the Bibliothèque nationale de France.”
