Granite houses of the Minho

In north-western Portugal, the house is born of the stone beneath one’s feet. The subsoil of the Minho is a vast massif of granites, and it was with them — quarried on the very plot or in neighbouring quarries — that one of the most coherent and recognisable typologies of Portuguese vernacular architecture was raised over the centuries. The Minho granite house is not a single model, but a family of rural solutions that share the same material, the same humid climate and the same agricultural economy.

The block-house: livestock below, people above

The most widespread form is the so-called two-storey block-house, which gathers under a single roof both the dwelling and the farm. The ground floor, dark and cool, was the domain of work: stalls for the cattle, the wine cellar, the wine press and storage for tools. Above, on the main floor, were the kitchen with its stone hearth, the living room and the bedrooms. The heat of the animals rose and helped to warm the house — a simple thermal economy, attuned to the cold and rainy winters of the province.

The link between the two worlds is made by an external granite staircase set against the façade, which rises to a covered balcony or gallery. That porch is the heart of the Minho house: the entrance to the upper floor and, at the same time, a sheltered drying place where the ears of maize and the fruit were dried. The walls are of ashlar masonry, with large rectangular blocks laid in horizontal courses; the timber, often chestnut or oak, is reserved for the roof structures, the balconies and the interior carpentry.

The house and its world: threshing floor, well and granary

The house is rarely understood on its own. Around it is arranged a small universe of buildings supporting the farm work: the flagged threshing floor where the grain was threshed, the well, the straw ricks and, above all, the granary — the raised store, of granite and wood, where the maize dried, ventilated and sheltered from rodents. These granaries and corn-cribs are inseparable from the Minho landscape and, in groups such as those of Soajo or Lindoso, have become emblematic images of the North. The stone house, the threshing floor and the granary form a functional unity inseparable from the culture of maize, which from the seventeenth century onwards shaped the agriculture of the region.

In the Minho, it is hard to separate architecture from geology: the same stone builds the house, the granary, the field wall, the bridge and the wayside cross, giving the whole landscape a rare material unity.

From popular anonymity to heritage recognition

For a long time, these houses were regarded merely as utilitarian and anonymous construction. Their cultural appreciation owes much to the Inquérito à Arquitectura Popular em Portugal (Survey of Popular Architecture in Portugal), carried out between 1955 and 1960 by the then National Syndicate of Architects. Zone 1, devoted to the Minho, was studied by the team of Fernando Távora, Rui Pimentel and António Menéres, who documented and dignified these solutions, showing how learned architecture could learn from the constructive wisdom of the people.

Today, the Minho granite house is distinguished from its neighbours both by its material and by its scale. It is not to be confused with the schist houses of the inland mountains, of dark, layered stone, nor with the manor houses and seigneurial residences of the same Minho, where granite already serves the ostentation of coats of arms, baroque balconies and carved portals. Between the hut on the hill and the manor of the lord stretches the whole gradation of a building culture that made grey stone the signature of the rural North.
