The winery is located in the municipality of Pauillac in the Médoc (Haut-Médoc, Bordeaux) in the area of the same name. A direct neighbour is the famous Château Latour. It was created in 1850 by dividing the former Château Pichon-Longueville, the second part is opposite and is called Château Pichon-Longueville Comtesse (see the history there). The complete name mentioned on the label is "Château Pichon-Longueville au Baron de Pichon-Longueville". The estate is also often called "Château Pichon-Baron" for short.
In 1987, it was bought by the AXA insurance group and Christian Seely was appointed to manage it. Major investments followed, including the construction of a new fermentation cellar. In the 1855 Bordeaux classification, the estate was awarded second place (Deuxième Cru Classé). The vineyards cover 70 hectares of vineyards with the varieties Cabernet Sauvignon (70%), Merlot (25%) and Cabernet Franc (5%). The extremely long-lasting red wine is aged for 15 to 18 months in 70% new barriques. It is counted among the so-called "super-seconds", i.e. it would deserve the "Premier Cru Classé". The second wine is called "Les Tourelles de Longueville".
