Château Langoa-Barton, a Third Classified Growth, was the first of two Bordeaux estates acquired by Hugh Barton in the 1820s; the second being Château Léoville-Barton, a Second Classified Growth. Hugh Barton descended from an Irish family that settled in Bordeaux during the 18th century and established a prominent presence in the region's wine trade. Both estates remain under family ownership, representing the longest continuous lineage of ownership in the Médoc. Following the passing of Anthony Barton in 2022, his daughter Lilian and grandson Damien Barton have assumed leadership of the estates.
