Casa Amarela, National Coin Museum in KaMpfumo district, Mozambique.

Casa Amarela is a single-storey, L-shaped building with an inner courtyard and ochre exterior walls pierced by tall windows; it has no roof. It stands on Praça 25 de Junho and houses the Museu Nacional da Moeda, which holds over 4,300 items including coins, banknotes and medals.

The building was constructed in 1787 as one of the first stone structures in the trading settlement and later housed a governor. Its architecture reflects Portuguese influence during the period when the colony was developing as a commercial center.

The building shows how different things became money in this region and what people valued in trade. Visitors can see shells, metal pieces, and other objects that served as payment long before modern coins existed.

Plan enough time to explore the different rooms and exhibitions, as there is much to see in the collections. The interior courtyard helps with orientation and makes moving through the space more comfortable.

The building's name comes from the ocher paint on its unadorned outer walls, which gave it the name "A casa amarela" soon after an Indian merchant bought and remodeled it around 1860. The entrance has faced Praça 25 de Junho since that remodeling.
