This square is the very heart of the village of Montmartre. Here, you can admire the Église Saint Jean de Montmartre, and the Square Jehan Rictus, which replaced the town hall of the 18th arrondissement, and where Verlaine was married. In the centre of the square, the métro station is one of only two in Paris to have kept its original entrance, designed by Hector Guimard.
