Sé

One of Lisbon’s biggest icons is the fortresslike sé, built in 1150 on the site of a mosque soon after Christians recaptured the city from the Moors. It was sensitively restored in the 1930s. Despite the masses outside, the rib-vaulted interior, lit by a rose window, is calm. The treasury showcases religious gems, and the Gothic cloister houses archaeological excavations, including stonework from the 6th century BC, a medieval cistern and the Islamic foundations. Stroll around the cathedral to spy leering gargoyles peeking above the orange trees; the sé looks its best when the late-afternoon sun makes its bricks glow honey-gold.
