The Hassan II Mosque is the second largest mosque in the world and is located in Casablanca, the economic and business capital of Morocco. Michel Pinseau, a French architect, designed the Hassan Mosque and its accompanying minaret. Pinseau designed the building in such a way that it is able to endure earthquakes. At night the minaret has lasers that shine in the direction of Mecca. Today, the minaret is considered the tallest in the world, standing at 689 feet or 210 meters.
The mosque stands on a prominent piece of land that rises up on the shore of the Atlantic and provides visitors with the most spectacular views of the ocean. It was decided by King Hassan II that the mosque should be built on this location because of a verse found in the Qur’an, which says that God’s throne was built over the water. The King wanted worshippers to be able to see God’s creations like the ocean and the sea.
