By 1305 the business of the Regno was sinking into the background of French life and politics, although there were odd moments in which it came again to the forefront, for example with the marriage of Catherine de Valois and Philip of Taranto in 1313. But for long after this, there were places in northern France where the memory of the great adventure was kept alive, where inhabitants and visitors would pause to reflect on the past.

In Paris, there were several of these. Perhaps the one that will have attracted most attention, at least for some years, was the rue du Roi-de-Sicile in the Marais, which acquired its name from Charles of Anjou's hôtel, once situated on this street. The name will have been known to large numbers of people, both literate and illiterate, who went about their business in this increasingly busy part of the city. Every time they mentioned it, they will have had the image of Charles in mind. Then those who entered the Dominican church – the well-known one on the rue Jacob, at the heart of the university – will have found some indication of the burial place of Charles of Anjou's heart, sent there after his death in January 1285. According to Alexis de Saint-Priest, the casket in which it was kept was inscribed ‘le coer di grand roy Charles qui conquit Sicile’. In 1309 Marguerite of Tonnerre's heart came to the same place.
