Portuguese Azulejo

No other European country has made the azulejo such a structural element of its visual culture. Portuguese azulejo art is perhaps the most identity-defining of the country’s decorative arts: over five centuries, Portugal covered the interiors and façades of churches, convents, palaces, staircases, atria, stations and gardens with glazed ceramic cladding, transforming an imported technique into a distinctive visual language — so much so that in the seventeenth century it became Europe’s largest producer of azulejos.

More than an incidental ornament, the Portuguese azulejo combines function and language: it protects and cools walls, controls light, organises architectural space and, above all, narrates sacred and secular episodes, fixing a visual memory of the cities. Through its historical continuity and the scale on which it covers the territory, it constitutes a central chapter of Portuguese decorative arts and an unavoidable element of the national built heritage. To trace its history is to trace the history of Portuguese art itself.

The word and the Hispano-Moresque arrival

The term azulejo derives from the Arabic az-zulayj, «small polished stone», and refers to the cut mosaics (alicatados) of the Islamic tradition of the Iberian Peninsula. Despite the image we now associate with it, it has no etymological relation to the colour blue.

The first azulejos reached Portugal at the end of the fifteenth century, imported from Seville and Toledo: geometric patterns in the Islamic tradition, in which modular repetition covered the wall like a carpet. The Mudéjar techniques of the Hispano-Moresque tradition then predominated, designed to prevent colours from mixing during firing: corda seca, which separated the glazes with a greasy line, and aresta, in which small raised clay walls held each colour in its own channel.

Around 1500, King Manuel I, dazzled by the wall coverings he had seen in Spain, had rooms of the Palácio Nacional de Sintra clad with Hispano-Moresque panels from Seville. Some of the oldest ensembles in the country survive there.

Maiolica: from pattern to figure

The decisive turn came in the mid-sixteenth century, with the arrival of Italian-influenced faience and the maiolica technique: by covering the azulejo with an opaque white tin glaze, it became possible to paint directly on the surface, as on a canvas. Freed from the geometry of the mould, the azulejo ceased to be merely pattern and could become figure: it opened to composition, perspective and, eventually, narrative.

The first local workshops in Lisbon emerged, establishing domestic production, along with figurative compositions such as the panel of Nossa Senhora da Vida. Early examples of this new ceramic painting are also the Renaissance panels of the Quinta da Bacalhoa.

The seventeenth-century pattern

The seventeenth century consolidated the taste for repeated pattern. The seventeenth-century repeated-pattern azulejo developed, in which polychrome modules multiply to form continuous carpets of great decorative effect. It was also the period of the first great church revetments, such as those of the Church of São Roque in Lisbon.

The Baroque azulejo: blue and white and the age of the masters

In the last quarter of the seventeenth century, and generally by around 1700, the blue-and-white monochrome became dominant, inheriting from Chinese export porcelain, Delft faience and European engraving. By privileging drawing over colour, this option allowed compositions of enormous theatrical ambition and opened the golden age of the narrative azulejo, which extended through the first half of the eighteenth century.

The Baroque azulejo covers entire church naves with hagiographic cycles and biblical histories, and fills palaces with mythological, hunting, battle, courtship and everyday scenes. Frames, painted columns and life-size figures extend real space into the wall.

The Baroque azulejo does not decorate architecture: it dissolves its walls, opening them onto illusory spaces that extend the building beyond its limits.

This is the so-called age of the masters, in which the figure of the mestre azulejador (master tile painter) emerges and, with it, the authored workshops. Gabriel del Barco, a Spanish painter established in Lisbon, is a transitional figure; his workshop is credited with the Grande Panorama de Lisboa (c. 1700), a panel of more than twenty metres recording the city before the earthquake of 1755. There follow António de Oliveira Bernardes and his son Policarpo, authors of vast figurative programmes of remarkable coherence, who raised the panel to a theatrical virtuosity capable of rivalling fresco painting, and masters such as Bartolomeu Antunes. In churches, these tiled settings engage with Portuguese Baroque painting and gilded woodcarving.

From the Pombaline azulejo to the nineteenth-century façade

The 1755 earthquake and the Pombaline reconstruction of Lisbon brought a pragmatic turn. For the buildings of the Baixa, the Pombaline pattern became widespread: modular, sober and mass-produced, faster and cheaper than figurative panels, serving an urban programme and the utilitarian spirit of the new city. The Royal Porcelain Factory of Rato began supplying the reborn city.

In the nineteenth century, semi-industrialisation, stencilling and Brazilian influence popularised the façade azulejo: for the first time, entire buildings were clad in ceramic, turning ordinary streets into luminous, washable surfaces. Thus was born the tiled urban landscape that still distinguishes cities such as Lisbon, Porto, Aveiro and Ovar.

Art Nouveau, modernism and public art

At the turn of the century, interpretations of Art Nouveau emerged and, in the twentieth century, the azulejo recovered its artistic ambition and asserted itself as a medium of public art (see Art Nouveau and modern azulejo). Jorge Colaço executed large monumental panels in a historicist vein; Jorge Barradas, Querubim Lapa and, above all, Maria Keil — author of the wall coverings of the first stations of the Lisbon Metro — reinvented the azulejo as modern art, restoring to it an abstract dimension and closing the circle between the medieval pattern and contemporary creation.

This uninterrupted vitality distinguishes the Portuguese case within the European panorama of glazed ceramics and ties it closely to the broader tradition of Portuguese ceramics and faience. The workshop knowledge that sustains it is treated in traditional Portuguese azulejo.

How to look at a panel

Reading an azulejo means attending to three things at once: the module (the unit that repeats), the palette (which almost always dates the piece) and the relationship with the architecture it covers. A panel cannot be understood in isolation from the wall it clads — it was conceived for that wall, and for it alone.

Where to study Portuguese tilework

The full history of this art, from the Mudéjar mould to the contemporary panel, is gathered at the Museu Nacional do Azulejo, in Lisbon, housed in the former Convent of Madre de Deus. Its collection, the most complete in the country, documents the evolution of Portuguese azulejo art from the sixteenth century to the present day.
