At the corner of the biggest urban park of the city, a new home is planned for the museum of the cultures of the world. Our proposal emphasised the corner position moulding the building as a triangle with a curved side embracing the green mass of the park. From both sides of the urban crossing, as well as from the park, the visitors have access to the main central hall digging the volume from the ground floor to the top. All the exhibition areas, the shops and the services are facing on the high void space through wide terraces. While the introverted space offers itself as a square for the city, the external interface of the building is as solemn and mute as a monument. The function is revealed by the constellation of variously shaped openings, representing windows from all the architectural cultures of world appearing behind the translucent skin.
