“Chappe” semaphores, the ancestor of the telegraph, were placed at the top of the towers until 1850, to transfer messages between Paris and the rest of the country.
  

The southern tower of Saint-Sulpice was designed by Oudot de Maclaurin. The northern tower was designed by Jean-François Chalgrin, and is thus quite different. The southern tower was never finished, for lack of funds, and because of the French Revolution.
