Casa de Ferro, Iron building in KaMpfumo district, Mozambique

Casa de Ferro is a building in Maputo composed of iron plates and steel components that were imported from Belgium to this coastal city. The structure was assembled using prefabricated metal parts designed to fit together as a complete architectural unit.

The building was constructed in 1892 and was originally intended as a residence for the Portuguese colonial governor but proved unsuitable due to heat. The prefabricated metal design came from Belgian workshops as an experimental approach for tropical climates.

The structure reflects Mozambique's connection to European industrial methods of the 1800s through its all-metal design and imported components. Today it serves as office space for the Ministry of Culture, linking the colonial past with present-day government work.

The Casa de Ferro stands at the corner of Avenida Samora Machel and Rua Enrique de Sousa, beside the Tunduru Gardens. It was moved there in 1966 from Avenida 5 de Outubro. The building now houses Ministry of Culture offices and is open to visitors; the iron panels and pierced ventilation holes near the ceilings are best seen from inside.

The Casa de Ferro is often wrongly credited to Gustave Eiffel, but it was built in Belgium using the Danly system patented by engineer Joseph Danly, who developed it for the Belgian Congo. The same system was used for the Casa de Fierro in Peru.
