5 Best Sights in Lisbon, Portugal

A standout on Lisbon's skyline, this gleaming white basilica was built in the baroque and neoclassical styles. Its location at the top of one of Lisbon's seven hills makes for dramatic views from its rococo zimbório (dome). It was built at the end of the 18th century under the command of Queen Maria I (whose tomb lies within the building) to fulfill a religious promise she made while praying for a male heir. The interior is striking, too, with black-and-pink marble walls and floors and a famously elaborate nativity scene displayed year-round.

If you see only one historic landmark in Belém, make it this magnificent monastery. This UNESCO World Heritage site is a supreme example of the Manueline style (named after King Dom Manuel I), which represented a marked departure from earlier Gothic architecture. Much of it is characterized by elaborate sculptural details, often with a maritime motif. João de Castilho was responsible for the southern portal, which forms the main entrance to the church: the figure on the central pillar is Henry the Navigator. Inside, the spacious interior contrasts with the riot of decoration on the six nave columns and complex latticework ceiling. This is the resting place of both explorer Vasco da Gama and national poet Luís de Camões. Don't miss the Gothic- and Renaissance-style double cloister, also designed to stunning effect by Castilho.  Lines can be especially long here; buy a timed ticket in advance.

Lisbon's austere Romanesque cathedral was founded in 1150 to commemorate the defeat of the Moors three years earlier. To rub salt in the wound, the conquerors built the sanctuary on the spot where Moorish Lisbon's main mosque once stood. Note the fine rose window, and be sure to visit the rooftop terrace and the treasure-filled sacristy, which contains the relics of the martyr Saint Vincent, among other things. According to legend, the relics were carried from the Algarve to Lisbon in a ship piloted by ravens; the saint became Lisbon's official patron. The cathedral was originally built in the Romanesque style of the time but has undergone several rebuilds and refurbishments over the years; today its rather eclectic architecture includes Gothic, baroque, and neoclassical adornments. Visitors are expected to dress respectfully.

One of Lisbon’s hidden treasures, the exterior of this 17th-century convent belies the riches inside. Still inhabited by nuns and women in need, it opens for visits every day except Tuesday, starting in the beautiful church lined with Portuguese and Dutch tile panels. They’re found below paintings framed by gilded wood carvings, which, together with the gold-and-marble altar, make it one of Lisbon’s most notable examples of Portuguese baroque.

The Italianate facade of the twin-towered St. Vincent's Monastery heralds an airy church with a barrel-vault ceiling. It's the work of three architects including Spaniard Juan de Herrera (1530–1597) and Italian Filippo Terzi (1520–97) and was completed in 1629. Its superbly tiled cloister depicts the fall of Lisbon to the Moors. The monastery also serves as the pantheon of the Bragança dynasty, which ruled Portugal from the restoration of independence from Spain in 1640 to the declaration of the republic in 1910. It's worth the admission fee to climb up to the rooftop terrace for a look over Alfama, the dome of the nearby Santa Engrácia, and the river. Guided tours of around 90 minutes are available for a modest extra charge, but must be booked in advance.
