Saint-Jacques Tower, the Tour Saint-Jacques, is a monument located in the 4th arrondissement of Paris, on Rue de Rivoli at Rue Nicolas Flamel. This 52 metres (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.
The church, with the exception of the tower, was demolished in 1793; preservation of the tower was a condition of the contract by which the church was bought for the value of its building materials. In 1824 it was being used as a shot tower to make small shot. It was repurchased by the City of Paris in 1836 and declared a Monument Historique in 1862. A statue of the saint was installed on the top of the tower during the 19th century.
