Known as one of the cathedrals of wine, the building was designed by the renowned architect Lluís Domènech i Montaner in 1913. Recent works have focused on technical upgrades and preserving the structure, which is recognized as a National Cultural Heritage site.

Visitors can explore the cellar's iconic brick arches and the Castell d'Or bottling plant on a free 20-minute self-guided tour. The experience ends with a traditional wine tasting using a 'porró', a classic Catalan vessel that the winery aims to keep as part of the local culture.

The site is open during the cooperative shop's hours, with no prior booking required for groups under 10 people. The winery remains fully operational, supported by over 200 local members who continue the region's long-standing viticultural tradition.
