Bodegas Protos is an aspirational wine co-operative in Peñafiel, north-west Spain. The five parallel arches of the great roof sitting on a stone plinth provide a magnificently memorable image for the Bodegas on its site overlooked by the fine medieval Castle of Peñafiel . The handsome laminated timber trusses spring from the level of the plinth, while the terracotta tile-covered roof floats free of the purlins by means of steel arms. Inside the building visitors find themselves overlooking a double-height space, with the fermentation and storage vessels below them. Descending the spiral steel and glass stair visitors gain sudden views of the castle through the glazed gable of the arches far above them. This is a very memorable building.
