01 - Saint-Jacques Tower (Tour Saint-Jacques) is a monument located in the 4th arrondissement of Paris, France, on Rue de Rivoli at Rue Nicolas Flamel. This 52-metre (171 ft) Flamboyant Gothic tower is all that remains of the former 16th-century Church of Saint-Jacques-de-la-Boucherie ("Saint James of the butchery"), which was leveled shortly after the French Revolution.
