The Grande Mosquée de Paris hides a marble courtyard behind a plain white wall. A band of hand-cut tile runs round the lower walls, under arcades roofed in green glazed tile, and no two pieces are quite the same size. Gardens take up half the site beyond the courtyard. Water leaves the fountains in narrow channels, drops among the columns and runs past fig trees, apple trees and roses. A minaret stands over it all, though it never calls to prayer.
The mosque was raised as a thank-you to the tens of thousands of Muslim soldiers who died fighting for France in the First World War. Parliament voted the money soon after, the city gave the ground, and it opened in 1926 as the oldest mosque still in use in mainland France. Craftsmen came from Fez and Meknes to lay the tile. During the German occupation the rector, Kaddour Benghabrit, told his staff to give Jews false papers naming them as Muslims; survivors testified to this, and historians still dispute how many were helped. It is a working mosque, so the prayer hall is not always open to visitors.
