Cèsar Martinell i Brunet (Valls, 24 December 1888 - Barcelona, 19 November 1973)[1] was a Catalan modernista architect.

He became famous for the many wine cellars he made for the agriculture cooperatives of different towns throughout Catalonia, especially in the south, in the Province of Tarragona.

His masterpieces were his designs for wineries, which are called the cathedrals of wine (les catedrals del vi) due to their magnificence.

His wine cathedrals are located in several cities of Catalonia such as Falset, Nulles, Cornudella de Montsant, Montblanc and Gandesa, and some of them can be visited.

[2] He also designed the flour mill of Cervera and he managed restoration projects, such as the Basilica of Santa Maria in Igualada.
