English: Ceiling of the parish Church of Saint Sebastian (in Portuguese «Igreja Paroquial de São Sebastião»), Setúbal, Portugal. The original church of São Sebastião was a small hermitage, built around 1490 on the site of the current viewpoint of the city of Setúbal. The current parish church of São Sebastião, located in the Dominican convent, was founded between 1564 and 1566, in a work sponsored by D. Sebastião. The design of the temple is attributed to Afonso Álvares, royal architect who built the churches of São Roque, in Lisbon, and Espírito Santo, in Évora. The work of the church of São Sebastião de Setúbal stands out for the military design of its structure, certainly derived from the training of Afonso Álvares as a military engineer. The interior, with a single nave, has interconnecting side chapels, and was originally covered by a barrel vault, destroyed in the earthquake and replaced by a wooden roof. Although it is not a Jesuit temple, its design fits into an architectural typology disclosed by the Society of Jesus in the second half of the 16th century, resulting in a building of large proportions, with a large and bright interior space, preceded by an imposing and austere façade. Although it has undergone some structural changes, the church of São Sebastião can be defined as "a remarkable building in the evolution of Portuguese architecture in the second half of the 16th century" and is listed as National Portuguese Monument (Idem, p.50).
