The project involved the restoration of the prestigious Victoria Eugenia Theater in San Sebastián . This restoration was a challenging undertaking, as it required exact replication of all the interior elements, cast by the same architects in Carrara White Marble.

During this renovation of the theater, the interior elements—molding, staircases, flooring, columns, carvings, fireplaces, borders, and numerous artistic elements—were crafted in Carrara White Marble. For this renovation, Cuellar Stone transported all the plaster elements to its factory in Almería to make an exact replica for later installation in the theater.

Finally, it is worth noting that all the balusters that make up the main staircase have a different design from one another, being exact replicas in natural stone of the previous plaster ones.
