Saint Pierre is a church of 1400, a work of art and history. The best known, the Sacre Coeur, was never accepted by Parisians who called it the wedding cake, so, contemptuously. Montmartre is one of the places that I visit most and I always feel it is very special, I feel part of everything as if I had been born there. The thought of going up the hill Clichy, with pavements more than a thousand years, is like a party day for me! When I travel in any part of Paris (except pompidou) I have an incredible party in my soul! Do not miss St Pierre, but worth the visit thoughsomewhat abandoned. Hugs from Buenos Aires.
