On leaving the village for Atalaia by Route 115 there is the gate to the farm, with a cypress tree on each side; the paved driveway leads to the farm buildings, which include the manor, part of which dating back to the 17th century, wine cellar, stables, garages for horse-drawn carriages and several other annexes for the many farm activities.

Some of these buildings date back to long ago, while others are recent. Even when the estate was entailed to António Lobo do Torneio, in the 17th century, the chapel and the south wing, with its turret, were already there. The subsequent building took place to the north, with another turret from the 18th century connecting to the wine cellars and therefore closing the yard; the entrance to this is then the eastern gate. Before that, there was a small tunnel from the side of the chapel and under the house. The old paved driveway which followed the western side of the original building led to the tunnel.

In the second half of the 19th century, the then Viscount of Merceana, José de Menezes Jacques Lobo do Torneo, who was the last tenant of the entailed estate, played an important part in fighting phylloxera, which was destroying many European vines, having started in France. Even then, the farm produced quality wines, exported to France through Bordeaux. However, the disease soon entered Spain and from there passed to the Douro region and the rest of Portugal. Together with the Viscount of Chanceleiros, a good friend of his, he began fighting the virus.

When he became aware that some treatments were ineffective and others too expensive, he decided to import from America stems which resisted the disease; he not only used them to recover his vineyards, but also traded them, therefore contributing to the recovery of many other Portuguese vineyards. On the other hand, he was responsible for the building of new stables which are now used for wine tasting, meetings and launching and for tourist activities.
