The Ibrahim-al-Ibrahim Mosque, also known as the King Fahd bin Abdulaziz al-Saud Mosque or the Mosque of the Custodian of the Two Holy Mosques, is a mosque located at Europa Point in the British overseas territory of Gibraltar, a peninsula connected to southern Spain. The mosque faces south towards the Strait of Gibraltar and the African country of Morocco just a few kilometres away.
The building was a gift from King Fahd of Saudi Arabia and took two years to build at a cost of around £5 million. It was officially inaugurated on 8 August 1997.
It is the southernmost mosque in continental Europe, and is one of the largest mosques in a non-Muslim country.
The mosque complex also contains a school, library, and lecture hall. It is the only purpose-built mosque in Gibraltar to serve the Muslims in the territory who number over 2,000: around 4% of Gibraltar's total population.
