Among the valleys of the Douro River, near the left bank, in the village of Cambres, Lamego county, in the heart of the first Pombaline demarcation of the Region, is Quinta da Pacheca, one of the most prestigious and recognized properties in the Douro Demarcated Region. The history of the vineyard in this property dates back to the XVI century when it was a collection of vines that belonged to the Monasteries of Salzedas and St. João de Tarouca, as referred to in a document dating 1551. The estate is mentioned for the first time in a document dat- ed from April 1738 where it is referred to as “Pacheca”, a feminine form of the family name Pacheco for being owned for a lady, Da. Mariana Pacheco Pereira, an im- posing woman who took care of the property by herself. One of the Pombaline landmarks remaining that were first used in 1758 to outline this first ever Demarcated Wine Region in the world by the Marquês de Pombal, is still preserved inside Quinta da Pacheca, right at the main entrance to the traditional stone tanks. These granitic stone marks were declared property of national interest in the 1940s. It was in 1903 that D. José Freire de Serpa Pimentel bought the property and began to work on the modernization of the vineyard and structures among which are eight granite stone tanks where red wines from Pacheca are still vinified, resulting in limited annual productions of special categories Douro DOC wines and Port wines.
