the Louvre courtyard, the presentation of Christ´s crown of thorns, a prehistoric merry-go-round, a sundial designed by Dalí, war-wounded palm trees, bullet holes at the ministry, biblical plants in a priest´s garden, a mysterious monument to freemasonry at the Champ-de-Mars, a solid gold sphere in parliament, a Chinese temple in a parking lot, the effect of the Bièvre 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.
