Lisbon Cathedral

Building began soon after the Christian conquest of 1147, probably on the site of the main mosque, which is why it looks like a fortress: two crenellated towers with a rose window between them. Earthquakes, above all that of 1755, meant parts of the interior and cloister had to be rebuilt.

In the cloister, excavations have uncovered a Roman street and Islamic and medieval remains. Upstairs, the high choir and the balcony between the towers look down the nave, and the treasury holds the cathedral's silverware and vestments.
