Leiria's 16th century cathedral (Sé de Leiria) lies just beyond the old city walls in a small square. It was constructed between 1559 and 1574, during the reign of Dom João III to designs by architect Afonso Alvares.
The earliest Jesuit church in Portugal and one of the first in the world, the Igreja de São Roque was built in the 16th century specifically for preaching.
Igreja do Divino Salvador, Matriz de Alvor (Church of the Divine Saviour) dates back to the 16th century, as does its best feature, the Manueline styled doorway.
Like many of Portugal's early cathedrals the Sé da Guarda appears part church, part fortress. Plans for the cathedral date back as far as the early 13th century, a time when much of Portugal had only just been clawed back from the Moors and wars with nearby Spain were constant.
Reputed to be the oldest building in Lisbon, the cathedral (Sé de Lisboa) certainly has the appearance of being built to last.
