In Portugal, the use of azulejos (glazed ceramic tiles) in architecture has a long history, extending uninterruptedly from the late 15th century to the present 21st century. For more than five centuries, the azulejo reinvented itself periodically to meet the demands of different historical periods, and one of its most expressive transformations took place in the Baroque period (1675–1750). Baroque azulejos stand out not only for the almost exclusive use of blue and white painting, but above all for the exploration of narrative programs, which were displayed in vast ceramic walls. These decorations covered the interiors of different buildings, but mostly churches.
The use of azulejos, dominating the interiors or in connection with other arts, was instrumental in creating a unique spatial form, which echoed Baroque spirituality by appealing directly to the senses and exploring the brightness and color of the tiled surfaces within majestic and lusciously decorated settings. But the azulejo was also a medium for religious painting and, as such, a vehicle for the doctrine and values of the Counter-Reformation, which were dominant at the time. Therefore, these ceramic architectural programs resort both to devotional and visual discourses. On the one hand, azulejo compositions relate to central aspects of Christian faith and liturgy, and particularly to the religious discourse and practice of the Baroque period. On the other hand, their visual features add new layers of meaning, mostly related to the organization of azulejos within a church’s architecture, the frames and inspirational sources, as well as issues linked with the creation and running of azulejo workshops.
