Defined by the playwright Àngel Guimèra as one of the cathedrals of wine, the modernista cellar of Pinell del Brai is the architectural expression of the agricultural cooperatives in Catalonia at the end of the 19th century. Its construction, in 1919, was the responsibility of Cèsar Martinell who used all the elements of the traditional Catalan architecture, the modernista aesthetic, and enriched it with the technical innovations of his teacher Antoni Gaudí.

The light that is filtered from the windows, the floor plan reminiscent of a church and the feeling of spaciousness recreates the interior of a Gothic Cathedral. But beyond the architectural beauty of the building, Martinell created a functional space designed for the production of wine. For this reason, some important technical innovations were incorporated: the structure of the warehousing based on parabolic arches, the ventilation system through large windows or insulation in the cavity walls of the containers in which the wine is made.

The most characteristic element of the winery is undoubtedly the glazed ceramic frieze on the façade designed by the painter Francesc Xavier Nogués, where there are scenes of the harvest and the production of wine and oil. Despite it being spectacular, due to the lack of budget, it was taken out of the initial project and was not incorporated until 1949.
