Freedom of religion in Algeria
Freedom of religion in Algeria is regulated by the Algerian Constitution, which declares Islam to be the state religion (Article 2) but also declares that "freedom of creed and opinion is inviolable" (Article 36); it prohibits discrimination, Article 29 states "All citizens are equal before the law. No discrimination shall prevail because
of birth, race, sex, opinion or any other personal or social condition or circumstance".
In practice, the government generally respects this, with some limited exceptions. The government follows a de facto policy of tolerance by allowing, in limited instances, the conduct of religious services by non-Muslim faiths in the capital which are open to the public. The small Christian and tiny Jewish populations generally practice their faiths without government interference. The law does not recognize marriages between Muslim women and non-Muslim men; it does however recognise marriages between Muslim men and non-Muslim women. By law, children follow the religion of their fathers, even if they are born abroad and are citizens of their (non-Muslim) country of birth.
Ghardaïa
Ghardaïa is the traditional heart of the M'zab valley and home of the Ibadi religious sect in Algeria. As a religious Muslim sect, they do not subscribe to the doctrine of Sunnism and Shi'ism. They practice a different way of praying, worshipping of God, and designing mosques compared to Malikis, the majority of Algerians. The wastage of water, and more generally any gift of land, is considered a sin. The Ghardaïa Mosque, built in the 10th century, is of Moorish architecture style. Its tower, simple and elegant, includes a large portal at the top of the shaft, the design of which provides for ventilation flow.
