Rossio, today Praça Dom Pedro IV, was one of the principal public stages of the Portuguese Inquisition in Lisbon. The autos-da-fé, formal ceremonies where inquisitorial sentences were read and penalties imposed, were staged here as urban spectacles designed for maximum visibility. Many of Lisbon’s processions began at the doors of the Church of São Domingos, on the edge of Rossio, immediately beside the Palácio dos Estaus, which served as the seat of the Lisbon tribunal of the Holy Office from the second half of the 16th century.

The scale of inquisitorial activity is measurable. Quantitative studies commonly cite 44,817 proceedings (processos) opened between 1536 and 1767, noting gaps for Goa in part of the 17th century. The same scholarship emphasizes that the principal targets of prosecution were New Christians of Jewish origin, and in Lisbon, “Judaism” remained a majority category of accusation, even within a more diverse imperial and cosmopolitan jurisdiction.

Rossio’s inquisitorial geography is also reinforced by archival preservation. The Arquivo Nacional da Torre do Tombo reports 19,775 descriptive records and 2,392,997 digitized images available online for the Inquisition of Lisbon collections, reflecting the volume of surviving documentation connected to Lisbon’s tribunal and its overseas jurisdiction.

The ceremonies themselves followed a fixed logic, public humiliation, ritualized penitence, and the reading of sentences before crowds. While executions were often carried out elsewhere, Rossio functioned as the symbolic center where guilt was proclaimed in public and social stigma was imposed. In the late 17th century, Rome increasingly pressured for punishments to be applied in more private settings, and by the 18th century the public auto-da-fé was in decline.
