The Most Beautiful Castles, Palaces and Fortresses in Portugal
15 places · updated 13 October 2026
In short: By our ranking, the most beautiful castles, palaces and fortresses in Portugal are Quinta da Regaleira, Belém Tower and Fort of Nossa Senhora da Graça, Elvas. The list covers 15 castles, palaces and fortresses. Last updated 13 October 2026.
Portugal's castles and palaces follow the country's history closely. Its long land border with Castile was guarded by hilltop castles from the age of the Reconquista, its seaborne empire produced the ornate Manueline style of the early sixteenth century, and its kings later built palaces fed by Brazilian gold. In the nineteenth century the hills of Sintra became the stage for Romantic fantasy, so the old frontier and the dream architecture sit only hours apart.
Sintra alone supplies a whole chapter. The Pena Palace, created for King Ferdinand II, paints its towers yellow and red on a hilltop above the forest; the Castle of the Moors runs its walls along the ridge below; Sintra National Palace is marked by its two conical kitchen chimneys; Monserrate mixes Gothic and Moorish motifs, and Quinta da Regaleira hides an initiation well whose spiral stair descends into the rock.
Elsewhere the defensive tradition takes over. Belém Tower stands in the Tagus at Lisbon, carved with Manueline rope and armillary spheres. The Castle of Almourol occupies a small island in the same river, Marvão's castle tops a granite crag looking into Spain, and the Fort of Nossa Senhora da Graça at Elvas is a star fort on a hill above a garrison town. Off the coast, the Fort of São João Baptista sits on an islet of the Berlengas reached by a narrow stone bridge, while the Palace of Mafra shows royal ambition on a monumental scale.

01 Quinta da Regaleira
Portugal · 23.1 km from Lisbon38.796° N 9.396° W
- UNESCO World Heritage
Diego Delso · CC BY-SA 4.0 The palace itself is a vertical fantasy of pinnacles, gargoyles, carved capitals and a slim octagonal tower, fronted by a loggia whose stone columns shelter tiled scenes of a royal hunt. Inside, five floors run from the servants' quarters and kitchen, with its food lift, to Monteiro's study; one room is lined with portraits of the kings of Portugal.
Did you know? The underground passages are lined with rough limestone brought from the coast near Peniche, chosen to make the tunnels feel like a submerged world.
02 Belém Tower
Torre de Belém
Portugal · 7 km from Lisbon38.691° N 9.216° W
- UNESCO World Heritage
Image by oneras from Pixabay Its architect, Francisco de Arruda, had built Portuguese fortresses in Morocco, and the tower mixes military purpose with the exuberant ornament of the Manueline style. Carved stone ropes and knots, armillary spheres and the crosses of the Order of Christ cover the limestone, while the domed watchtowers and balconies show Moorish influence.
Did you know? Work began around 1514 and was finished in 1519, just two years before the death of King Manuel I, who commissioned it.
03 Fort of Nossa Senhora da Graça, Elvas
Forte de Nossa Senhora da Graça
Portugal · 16.9 km from Badajoz38.895° N 7.164° W
mmmmngai@rogers.com · CC BY-SA 2.0 Lippe took as a model his own island fortress of Wilhelmstein in Lower Saxony. The plan is a square of roughly 150 metres with pentagonal bastions at the corners, four ravelins shielding the curtain walls, a hornwork and a deep dry moat, all wrapped in a star-shaped outer earthwork. The design was drawn by the French engineer Étienne and completed under Guillaume de Valleré.
Did you know? The same visitor recorded a very deep well whose water mixed with oil into a milky, unpleasant-tasting liquid, which he called a curiosity of natural history.
04 Castle of Marvão
Castelo de Marvão
Portugal · 12.4 km from Portalegre39.396° N 7.380° W
Elemaki · CC BY 3.0 The name of the place is traditionally traced to Ibn Marwan, a 9th-century Muwallad rebel who built a power base across much of what is now Portugal and is credited with fortifying the hilltop around 876–877. Christian forces under Afonso I took the area from Muslim rule in the 1160s; Sancho II granted Marvão its first charter in 1226, and in 1271 it passed to the Hospitaller Order, whose Maltese crosses still appear on houses in the village.
Did you know? Ibn Marwan, whose name the town carries, is also regarded as the founder of the Spanish city of Badajoz; his great-grandson submitted to Abd al-Rahman III in 929.
05 Pena Palace
Portugal · 22.3 km from Lisbon38.788° N 9.391° W
- UNESCO World Heritage
Singa Hitam · CC BY 2.0 The site was first a small Hieronymite monastery dedicated to Our Lady of Pena, which the great earthquake of 1755 left in ruins. In 1838 Ferdinand II, king consort of Queen Maria II, bought the ruins together with the surrounding land and commissioned the German mining engineer and amateur architect Baron Wilhelm Ludwig von Eschwege to turn them into a summer residence. Work ran from 1842 to 1854, though the main structure stood by 1847.
Did you know? The great window on the main facade was modelled on the celebrated Manueline window of the Convent of the Order of Christ in Tomar.
06 Castle of the Moors
Portugal · 22.4 km from Lisbon38.793° N 9.390° W
- UNESCO World Heritage
Ввласенко · CC BY-SA 3.0 A chapel of São Pedro inside the walls became a parish church in the 12th century, and in 1375 King Ferdinand I ordered the castle rebuilt. But the inhabitants were drifting down to the town of Sintra, and by the end of the 15th century the chapel was abandoned. The small Jewish community that used the site was expelled under Manuel I, and the castle was left empty. The 1755 earthquake badly damaged it.
Did you know? Local tradition long held that the chapel had been a mosque before the Christian conquest, but there is no evidence linking this building to Islamic worship.
07 Sintra National Palace
Portugal · 22.7 km from Lisbon38.798° N 9.391° W
- UNESCO World Heritage
Michael Gaylard from Horsham, UK · CC BY 4.0 A palace stood here under Moorish rule, when it was a residence of the rulers of the Taifa of Lisbon, and passed to Afonso Henriques in the 12th century, but nothing from that time survives. The oldest part of the present building is the Royal Chapel, possibly from the early 14th century, with a Moorish-style lattice ceiling.
Did you know? The Royal Chapel preserves what is considered the oldest Mudéjar ceramic and timber ceiling work in Portugal.
08 Castle of Almourol
Castelo de Almourol
Portugal · 36.3 km from Santarém39.462° N 8.384° W
Daniel Feliciano · CC BY-SA 2.5 The site is believed to have been fortified long before the Middle Ages; excavations have turned up Roman coins and foundations, and medieval medallions and marble columns have been found nearby. The castle passed to the Portuguese in 1129 and was entrusted to Gualdim Pais, master of the Knights Templar in Portugal, who rebuilt it; an inscription over the main gate dates the work to 1171.
Did you know? The Templars held Almourol as part of their task of settling the land between the Mondego and the Tagus and shielding Coimbra, then Portugal's capital.
09 Palace of Mafra
Palácio Nacional de Mafra
Portugal · 28.3 km from Lisbon38.937° N 9.326° W
- UNESCO World Heritage
Image by ofuss from Pixabay It began as a vow. In 1711 King John V promised to found a convent if his queen, Maria Anna of Austria, bore him a child; the birth of the Infanta Barbara set the project in motion, and the first stone was laid on 17 November 1717. What was planned as a modest house for 13 friars grew into a palace-monastery once gold and diamonds from colonial Brazil began pouring into Lisbon.
Did you know? The celebrations for the consecration of the basilica in 1730 lasted eight days, on a scale Portugal had never seen.
10 Palácio Hotel de Bussaco, Palacete Hotel do Buçaco
Palácio Hotel do Buçaco
Portugal · 20.1 km from Coimbra40.377° N 8.365° W
Soniapampa · CC BY-SA 4.0 The ground it occupies has a long religious history. In 1628 Discalced Carmelite friars founded the Convent of Santa Cruz do Buçaco here and planted around it an enclosed woodland of many tree species, meant to evoke Mount Carmel, the cradle of their order, and the Earthly Paradise. In the late 17th century they added a series of chapels along a Way of the Cross through the trees.
Did you know? Architect Luigi Manini had worked as a stage-set designer at Lisbon's São Carlos opera house, which helps explain the palace's theatrical look.

11 Fort of São João Baptista Berlengas
Forte de São João Baptista das Berlengas
Portugal39.411° N 9.510° W
Hugo Cadavez from Viseu, Portugal · CC BY 2.0 The Berlengas are a small archipelago of granite islets lying 10 to 17 kilometres off Peniche. Berlenga Grande, the largest, is only about 1.5 kilometres long, a plateau of pink granite, a rock rare in Europe, broken along its shore into caves, arches, coves and stacks. The islands are a nature reserve for seabirds, and in 2011 UNESCO added the Berlengas to its World Network of Biosphere Reserves.
Did you know? Even before the great siege, the fort's guns drove off an attack by three Turkish vessels in 1655.
12 Monserrate Palace
Portugal · 25 km from Lisbon38.794° N 9.421° W
- UNESCO World Heritage
Stavros Argyropoulos from Greece · CC BY-SA 4.0 The estate has a long history. A chapel dedicated to the Virgin stood here in the Middle Ages, and in about 1790 the English merchant Gerard de Visme built a neo-Gothic house over its ruins. The writer William Beckford rented the property in 1793–1794 and began to shape its grounds, and Lord Byron visited in 1809; his lines about it in Childe Harold's Pilgrimage drew foreign travellers to Monserrate.
Did you know? The great Lisbon earthquake of 1755 left the farmhouse that then stood on the estate uninhabitable, and it lay in ruins when Byron passed by.
13 Castle of Monsanto
Portugal40.036° N 7.114° W
Nmmacedo · CC BY-SA 3.0 The village is built directly into and around granite boulders far too massive to clear, which meant early builders used the rock itself as walls, roofs and floors rather than fighting it — a wedged-in, half-underground way of building that reads today as strikingly modern, even though it comes from necessity rather than taste.
Did you know? Royal surveys counted 309 inhabitants in 1496 and 494 by 1527, a glimpse of how small the fortified village was in its heyday.
14 Palácio da Bolsa, Porto
Portugal · 1.3 km from Porto41.141° N 8.616° W
Michael Gaylard from Horsham, UK · CC BY 4.0 The site belonged to the Franciscan convent of São Francisco, founded in the thirteenth century; its cloisters burned in 1832 during the Liberal Wars, and in 1841 Queen Maria II gave the ruins to the city's merchants. Construction began in 1842 to designs by the architect Joaquim da Costa Lima Júnior, in a neoclassical style with Palladian influence.
Did you know? Painters such as José Maria Veloso Salgado and António Ramalho contributed canvases and ceiling frescoes to the interiors.
15 Almeida Fortress
Praça-forte de Almeida
Portugal · 36.5 km from Guarda40.726° N 6.906° W
Fernando Gabriel · CC BY-SA 3.0 The plan is an irregular star of six bastions separated by six curtain walls, each curtain screened by a detached ravelin, so that the outline has twelve points in all. 5 km, the walls are faced with dressed granite, and the dry ditch in front of them is around twelve metres deep.
Did you know? The fortified area covers about 65 hectares, and its ditch varies in width from about 10 to 62 metres.
How this list is ranked
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
