Hôtel du District

The Hôtel du District is an administrative building in the Plateau district of Abidjan with concrete facades decorated with light quartz stone. It was built between 1954 and 1956 by architect Henri Chomette and follows mathematical proportions in its design.

This building was constructed shortly after World War II as Côte d'Ivoire was modernizing its administrative structures. Its forecourt became the site where Félix Houphouët-Boigny announced the country's independence from France in 1960.

The building shows how architects of the 1950s blended local quartz stones into modern concrete facades. This combination of regional materials with contemporary design reflects the architectural identity that people in Côte d'Ivoire were creating during this period of change.

The building stands at the corner of Avenue Delafosse and Boulevard de la République and can be viewed from outside. Note that the interior is not open to visitors since it remains an active administrative building.

Architect Henri Chomette applied the golden ratio to the facade design, a mathematical proportion that is rarely used in construction. This subtle application of mathematical harmony is barely visible to the eye but gives the structure a hidden sense of balance and order.
