A priest who blesses animals, wine producing firement, a tree in a church, an inverted phallus at a famous entrance, an atomic bomb shelter under the Gare de l'Est, a real Breton lighthouse near Montparnasse, unsuspected traces of former brothels, a patron saint of motorists, royal monograms hidden in the Louvre courtyard, the presentation of Christ's crown of thorns, a prehistoric merry-go-round, a sundial designed by Dali, war-wounded palm trees, bullet holes at the ministry, biblical plants in a priest's garden, a mysterious monument to freemasonry at the Champs-de-Mars, a solid gold sphere in parliament, a Chinese temple in a parking lot, the effect of the Bievre river on Parisian geography, a blockhouse in the Bois de Boulogne... For those who thought they know Paris well, the city is still teeming with unusual and secret places that are easily accessible.
