Located between Valcalepio and Franciacorta, in Villongo (BG), Podere Castel Merlo traces its origins back to a 10th-century fortified building. Acquired in the early 20th century by the Buelli family and incorporated into their wine estate, the castle has been transformed into a luxurious five-star Relais, adding a new chapter to the history of this enchanting Lombard gem.
