Arabisance

Algerian colonial architecture saw a shift in the early 1900s with the 1903 appointment of Charles Lutaud as Governor General. Lutaud advocated for the adoption of colonial cultural policy of Algerian "association" with France over Algerian assimilation, dictating that public buildings be constructed in the hybrid Moorish Revival Arabisance style. In reference to Lutaud's policies, the combination of Moorish architecture with European architectural styles in Algeria is sometimes referred to as the Jonnart style (French: Style Jonnart).
