La Basilique du Sacre Coeur

The hill in which La Basilique called "Montmartre" has been sacred since the Pagan times. The Druids are thought to have worshiped here, and also the Romans built temples to Mars and Mercury here. "Mons Martis" was the original name of Montmarte, which means "Mount of Mars, later on it became Christianized and has the name it has now. A competition was made in the 1800s to design La Basilique, the winner was "Paul Abadie". It is constructed of stone from Chateau-Landon, which is very known for its very high content of calcite. When the weather is damp, calcite comes out of the stone, which makes La Basilique look chalky white.
