Beyond the vineyards, the chance of heritage acquisitions combines the "small" history of Maison Drouhin with the “grand” history of Burgundy. It is first in an underground place that a first page is written, in the cellars of the historic Maison in Beaune, where the walls take us back fifteen centuries with the foundations of a Roman castrum. It bears witness to the importance of this ancient city through the remains of its enclosing walls.

This oratory housed the relics of Saint Baudèle, a bishop martyred by the Saracens in the 3rd century, before the construction of the Notre-Dame Collegiate Church in this location. Thus, Maison Joseph Drouhin is neighbour of the church and its college of canons. These canons cultivated many vineyards and were considered experts in their time. They already regarded the Clos des Mouches as the benchmark of Burgundy wines! Their cellars and “winery” were acquired and restored by Robert Drouhin in the early 1960s.

The buildings acquired by Joseph Drouhin include Maison du Diénat, which, among historians' hypotheses, was the residence of the dean of the Collegiate Chapter. This place still bears witness today to its vaulted cellars, its arched roof, its staircase with remnants of the tour d’Enfer, from the grand era of the Toison d’Or (Order of the Golden Fleece).

Above a portion of Maison Joseph Drouhin's cellars stands the Parliament of Burgundy, where justice was done. The Dukes themselves, from Philip Le Hardi to Charles Le Téméraire, presided over sessions there. Under Louis XI, the building became the residence of the King. One of Maison Joseph Drouhin's cellars served as cellars for the Kings of France. Conscious of the gifts received from a very long history, Philippe, Véronique, Laurent, and Frédéric protect this unique heritage, "a duty with an eye towards the future."
