Saint-Jacques Tower, the Tour Saint-Jacques, is a monument located in the IVe arrondissement of Paris, France. This 52-m Flamboyant Gothic tower is all that remains of the former church of Saint-Jacques-de-la-Boucherie ("Saint James of the butchery"). A statue of Blaise Pascal is located at the base of the tower, commemorating the experiments on atmospheric pressure, though it is debated whether they were performed here or at the church of Saint-Jacques-du-Haut-Pas.
