 The first mechanical clock in Paris appeared in 1300, and in 1341, a clock was recorded at the Sainte-Chapelle.It was not until 1370, under Charles V, who was particularly concerned by precise time, that a mechanical clock was installed on a tower of the Palace, which sounded the hours.Similar clocks were installed at the other royal residences, the hôtel Saint-Paul in the Marais and the Château of Vincennes.
