Starting from an ancient ruin of a grain mill that worked with hydraulic energy of an important ditch in the centre of town we designed a cultural centre that at approaches the didactic explanation of the grain mills history: the Centro Cultural “El Molino”. To maintain the identity of the ruins we decided to built a union between the ancient and the modern. The building is small but it has a great importance in the historic memory of Utebo people, for this reason and for being surrounded by housing we shaped an abstract volume without references to human scale and located quite far from the entrances to give it a kind of symbolic presence. We designed a square in front of the building, a teat cine that goes down towards the scenery made of stone vaults. This exterior hall is surrounded by walls, protected from wind and shaded by lindens. The ochre painted ferroconcrete, natural evolution of stabilized earth unify the whole building as if it's shaped in one material.
