10 Best Sights in The Algarve, Portugal

Widely considered one of the most remarkable examples of the Renaissance movement in the Algarve, this structure has a portal that dates to 1541. The church also hosts regular fado concerts—an unusual occurrence, but one that lifts the soul.

This early-18th-century baroque building is Lagos' most extraordinary structure. Its interior is a riot of gilt extravagance made possible by the import of gold from Brazil. Dozens of cherubs and angels clamber over the walls, among fancifully carved woodwork and azulejos. In an annex is the Museu Municipal Dr. José Formosinho, with a range of 18th-century artworks and archaeological findings.

This stunning 13th-century cathedral, flanked by cobblestone streets, whitewashed houses, and fragrant orange trees, is one of Faro's most beautiful monuments. Having survived transformations (including a past as a Roman basilica, then a mosque), earthquakes, and fires, the Sé retains a Gothic tower but is mostly of interest for the 17th- and 18th-century azulejos that fill its interior. On one side of the nave is a red chinoiserie organ, dating to 1751. Best of all, however, is the view from the top of the church tower (up some very steep stairs), looking out over Cidade Velha rooftops and across the lagoon.

One of the town's two major churches, Santa Maria was built on the site of a Moorish mosque in the 13th century. Although it was almost entirely destroyed by the 1755 earthquake, the church retains its original Gothic doorway.

This 13th-century church has handsome tiles, wood carvings, and an unusual wrought-iron pulpit. It was formerly a mosque, whose minaret is now a bell tower. The chestnut wood altar crafted by João Amado is an unusual find.

Just north of the city center, this baroque church looks very out of place amid the modern buildings surrounding it. Inside, a door to the right of the altar leads to the Capela dos Ossos (Chapel of the Bones) set in an outside garden area. The tiny chapel's walls are covered with more than 1,000 skulls and bones dug up from the adjacent monks' cemetery—an eerie sight, to say the least, but a fairly common custom in Portugal.

An earthquake devastated the original church that stood here, which dated to the 15th century. But the 18th-century restoration has a number of enchanting features; a collection of hand-painted tiles depicting dramatic biblical scenes, a Manueline portico with twisted columns that resemble knotted rope, a small art gallery, and an exhibition of centuries-old vestaments.

Though Praia da Luz has little in the way of sights other than its coastal attractions, it's worth stopping by this little church, shared by both the Catholic and Anglican communities around it with services in Portuguese and English. Though there's no historic clout to speak of, it makes a restful stop while in the town. The current 19th-century structure replaces a 15th-century church, destroyed by the 1755 earthquake.

This 16th-century sanctuary—perhaps the prettiest of Faro's churches—has an unusual altar set to the left of the main altar. It's entirely carved in gilded chestnut wood and a delicate frieze depicts the Last Supper. There's regular singing here, making for a spiritually uplifting break in the day.

The 12th- to 13th-century cathedral, built on the site of a Moorish mosque, saw service as the principal cathedral of the Algarve until the 16th century. The 1755 earthquake and indifferent restoration have left it rather plain inside, but its tower—complete with gargoyles—is still a fine sight.
