Designed by the famed French engineer Gustav Eiffel, this winery was built in honour of Queen Isabel II of Spain, who visited the winery in October 1862. Subsequent visits were made by the Spanish Kings Alfonso XII, Alfonso XIII and by King Juan Carlos and Queen Sofia. Within the winery are 214 casks of La Concha Amontillado bearing the flags of the 115 countries where González Byass wines are exported.
