Algarvian Houses

Algarvian houses are one of the most recognisable typologies of traditional Portuguese architecture, above all for the triad of elements that crown their façades and roofs: the açoteia (flat roof terrace), the platibanda (parapet) and the lace-like chimney. Whitewashed, cut out against the southern sky and populated with geometric motifs, the Algarve house is the product less of a learned school than of a popular building culture attuned to the climate, to local materials and to the ingenuity of master masons and whitewashers.

Roof terraces, pitched roofs and the single-storey house

The oldest structural feature is the opposition between flat covering and pitched roof. In part of the Barrocal and, emblematically, in Olhão, the house is covered by an açoteia — a flat terrace, often layered over several levels, that replaces the roof. It served to dry figs and carob, to catch the cool air and, from the heights of the mirantes (lookout turrets) and counter-turrets, to watch the sea and communicate with neighbours. It is to this system of whitened cubic volumes that Olhão owes its fame as a “cubist town”. To the east, in Tavira, the four-sided hipped roof prevails instead, with its brickwork treasure and steep pitch, giving the town a profile unique within the Portuguese panorama.

This diversity led some authors, such as the geographer Orlando Ribeiro, to read in them echoes of maritime contacts with the Mediterranean and the East, the fruit of the seafaring of Algarvian fishermen. Whatever the debated origins, these are solutions rooted in a territory of limestone, lime and intense light, close in spirit to other expressions of peninsular vernacular architecture, albeit with a grammar of their own.

Lace-like chimneys and parapets

If there is one symbol that has become the mascot of the Algarve, it is the lace-like chimney. Contrary to the myth that attributes a Moorish origin to it — fuelled by its resemblance to minarets — these chimneys only became widespread in the 17th and 18th centuries, at the height of Baroque taste; the oldest dated example known, in Porches, is from 1713. Cut out in plaster and lime over brick structures, they fall into several types — cylindrical, prismatic, “balloon” or grille — animated by openwork geometric designs.

It is said that the master stonemason would ask the owner of the work, “how many days of chimney do you wish?”: the more painstaking and costly, the greater the status it signalled — the chimney as the house’s discreet ostentation.

The platibanda, the decorative band that crowns urban façades while concealing the roof, completes this vocabulary. Painted in strong colours and geometric patterns, it frames doors and windows and, especially in the houses of the 19th and 20th centuries, turned entire streets of Olhão, Tavira and Loulé into a display of colour.

Documentation and safeguarding

The Algarvian house was systematically recorded in the Survey of Popular Architecture in Portugal (1955-1961), whose Zone 6 covered the Algarve and the Alentejo coast. That survey, today an essential reference, set down typologies, plans and photographs documenting a way of building that was then in accelerated transformation.

Neighbouring and contrasting is the Alentejan house, with its thick whitewashed walls and few openings against the heat of the plain; both share lime and an economy of means, but they diverge in the expression of the roof and its crowning. Integrated into the built heritage of the Algarve region, Algarvian houses remain threatened by urban pressure and by the replacement of handcrafted elements with industrial imitations. Their safeguarding hinges above all on the preservation of these details — açoteia, chimney and parapet — which, more than ornament, enshrine the technical memory and the identity of an entire region.
