Abstract In Algeria, which was colonised for over a century, the arrival of the French colonisers led to the introduction of new architectural styles imported from Europe. This adoption of an exogenous style in a different cultural context was only made possible by French military domination. Importing and imposing a style was not always easy, as Algerian resistance was as much stylistic and socio-cultural as it was military. To illustrate this point, we have taken the case of the historic city of Tlemcen (Northwest Algeria), where the French occupiers met with stylistic resistance complicating the achievement of their colonial project. Our research raises the following question: What forms of stylistic resistance are manifested in colonial architecture in the city of Tlemcen? Our aim is to identify the specific characteristics of colonial architecture in Tlemcen, in order to bring out the signs of stylistic resistance that testify to a desire to maintain a local cultural identity despite the colonial influence. The typological analysis of colonial facades serves as a tool and a means of providing in-depth understanding of architectural facades and typological classification in view of the diversity of styles and ornamentation of colonial facades in Tlemcen. This resistance manifests itself in European revivalism in Tlemcen, which involved an exceptional effort aimed simultaneously at composition and a search for stylistic anchorage and originality. It also manifested itself at the level of the native population, who stepped in to protect their cultural heritage and identity against the colonial authorities. Moreover, a certain form of stylistic reverence can be detected, expressed in avoiding pronounced aesthetic or stylistic expressions, favouring instead a more universal and timeless appearance.
