At one time, when Tangier was controlled by the Portuguese, the Mosque was converted into a cathedral.
Then, in 1684, at the end of a war won against the British, the Moroccans transformed the site into a mosque, which will be significantly extended in 1815.
The last expansion of what is now called the ''Grand Mosque'' was carried out in 2001 with the private funds of the King of Morocco, Mohamed IV. This work was however initiated by his predecessor, King Hassan II.
The main door of the structure will probably catch your attention due to its enormous size and its beautiful decoration, which stands out compared to the entire building's simplicity.
