The entire French city of Oran, Algeria, had to be adapted to the needs of a new population when Algeria won its independence in 1962. A similar problem emerged in the 1990s when the city was flooded by rural refugees fleeing the war between government and Islamist forces. Ten years ago Bel Horizon, a historic preservation movement, was founded in Oran; its objective was not only to preserve Ottoman, Spanish, and French buildings, but also to foster the habits and attitudes of citizenship, especially in young people. Bel Horizon's goals and successes are at once modest and profound. This case study suggests that historic preservation movements do not simply serve the purposes of cultural and political nationalism, as Rem Koolhaas and others have recently argued. Rather, it suggests that associations like Bel Horizon can help people to accept cultural mixture as part of their heritage.
