Extracted and translated from wikipedia: ca.wikipedia.org/wiki/Catedral_del_vi

A wine cathedral is, in the Catalan sphere, a cooperative winery with a large ship built in the Modernist style approximately between 1910 and 1920.

The architects that designed this type of construction are Cèsar Martinell (disciple of Antoni Gaudí) or Pere Domènech i Roura, among others. The denomination was created by Àngel Guimerà to refer, initially, to the Cooperative Winery of the Espluga de Francolí and later extended to the Cooperative Winery of Gandesa and other similar cellars. These buildings have in common their characteristic architectural style, as well as the size of the ships.

The name of the wine cathedral is explained above all by the aesthetics (for example, by the facade and the vaults of the ceiling) and by the dimensions. Keep in mind, on the other hand, that the beauty and other peculiarities of these works are linked to functionality. It is a specific conception of modernism, in which the aesthetics and functionality were built on the wall; and so is seen in many other modernist works that are wineries like the attic of La Pedrera in Barcelona, the Palace of Catalan Music of Barcelona, the Institute Pere Mata de Reus or slaughterhouses Modernist Tortosa among others.
