Square de la Tour Saint-Jacques
This square in the 4th arrondissement is home to the Tour Saint-Jacques, a 54-metre Flamboyant Gothic masterpiece, the last remnant of the Saint-Jacques-de-la-Boucherie church destroyed during the Revolution. It was the starting point for pilgrims heading to Santiago de Compostela.
A Unesco World Heritage site, the tower is decorated with statues of the four evangelists and of Blaise Pascal, who is said to have repeated his atmospheric pressure experiments here. The surrounding garden offers a green break in the very centre of Paris.
Tip: the tower can be visited on guided tours in summer, with an exceptional panorama from the top. Otherwise, allow 15 to 20 minutes in the square, steps from Châtelet.
