All that remains of the former Benedictine Abbey of Montmartre, this church dates back to the 12th century and is one of the oldest in Paris, though it has been much restored. Built atop a Roman temple to Mars, it was witness to the founding of the Jesuits in 1534, who met in the crypt under the guidance of Ignatius of Loyola.
Some say that the name Montmartre is derived from ‘Mons Martis’ (Latin for Mount of Mars); others prefer the Christian ‘Mont Martyr’ (Mount of the Martyr), a reference to the 3rd-century St Denis, who, according to legend, walked across Montmartre and on to the site of today’s Basilique de St-Denis after having been beheaded by Roman priests.
