15 Most Beautiful Castles in Portugal
Óbidos Castle
Óbidos Castle is one of the most picturesque in Portugal, with high walls stretching for about 1.5 km that surround the entire village, creating a postcard-perfect scene with breathtaking views.
It’s believed the castle has Roman origins, though what we see today are reconstructions by the Moors and later by the Christians during the 12th-century reconquest. Because it was built in different phases, the fortress combines Romanesque, Gothic, and Manueline styles, featuring a keep and several square towers.
Within the walls, three major annual events take place — the Medieval Festival of Óbidos, the Christmas Village, and the International Chocolate Festival. If you visit during one of these, expect even more fun and energy in the air.
Almourol Castle
Almourol Castle stands out from all the others for its unique location — on a tiny island in the middle of the Tagus River, near Vila Nova da Barquinha. Its mysterious vibe and connection to the Templars, who rebuilt it in the 12th century, make it even more fascinating.
Visiting is simple: head to the pier near the village of Almourol and take the small boat that crosses the river in under five minutes. The ticket costs about €4 and includes both the round-trip and castle entrance.
The visit takes around 40 minutes, enough time to wander along the walls, climb the towers, and reach the keep for stunning views over the Tagus. It’s a perfect family outing, and the best time to go is outside summer weekends when it’s quieter and the experience feels even more magical.
Guimarães Castle
Guimarães Castle is where it all began — and you can truly feel it in the air when you visit. It’s one of the most critical places in Portugal’s fight for independence, dating back to the days of the old County of Portucale.
Originally built in the 10th century to protect the local population from Viking and Moorish attacks, the castle was expanded several times, becoming one of Portugal’s most significant and most iconic monuments. Although it was abandoned for centuries after the invention of cannons, it was carefully restored in the 20th century to the impressive state we see today.
Besides being one of the most important castles in the country, it’s also one of the most striking and best-preserved. Don’t forget to climb the walls for panoramic views over the UNESCO-listed city and its surroundings.
Santa Maria da Feira Castle
Santa Maria da Feira Castle is one of the most distinctive symbols of Portugal’s medieval history, and when you visit, you can feel its strength and strategic importance. Located in the heart of Santa Maria da Feira, this fortress played a key role in defending the territory and consolidating power during the Middle Ages.
Its construction dates back to the 11th century, and it was expanded and reinforced over time to withstand attacks and maintain control of the region. Today, it’s considered one of the most impressive and best-preserved medieval castles in Portugal.
Walking along its walls and towers, it’s impossible not to be amazed by the panoramic views of the city and the surrounding landscapes. Santa Maria da Feira Castle isn’t just a historical monument — it’s a true journey back to medieval times. It’s also the stage for one of Portugal’s most famous medieval fairs, and during Christmas, the castle grounds turn into a charming holiday village.
Moorish Castle (Castelo dos Mouros)
From a distance, the Moorish Castle seems to hide within the Sintra hills, camouflaged among trees and mountains.
Built by the Moors during their occupation of the Iberian Peninsula, it once included a small fortified village with houses, walls, and silos for storing food and water. Later, it was conquered by King Afonso Henriques, abandoned when its defensive purpose was lost, and finally restored by King Ferdinand II.
This magnificent castle sits next to Pena Palace in the Sintra mountains. The road leading to both sites is closed to private cars, so the only way to reach them is by public transport, taxi, Uber, or a guided tour.
It’s a magical place surrounded by an enchanting forest — one of our absolute favorites for its views and history. It sparks the imagination and reminds us just how fascinating Portugal’s past is.
Silves Castle
Silves Castle is one of the most impressive historical monuments in the Algarve and stands out for its strong Islamic architectural influence. Sitting atop a hill, it offers sweeping views of Silves and the Arade River — blending history, culture, and landscape in one place.
The fortress dates back to the Moorish period, when it was built as a strategic stronghold. In 1189, it was conquered by King Sancho I. Yet, many of its original features were preserved, reflecting the deep Islamic influence evident in its walls, towers, and overall design. This feature truly sets it apart from other Portuguese castles.
Today, Silves Castle is beautifully preserved and open to explore in all its grandeur. Walking along its walls feels like stepping back in time and imagining what life was like during the Middle Ages.
Marvão Castle
Marvão Castle had to be on this list — it’s undeniably one of the most beautiful and best-preserved castles in Portugal. It also offers some of the most spectacular views, as it sits at the very top of the Serra de São Mamede range.
The best part of visiting is wandering freely through its towers, walls, and terraces. In the low season, it’s almost magical — you might even have the whole place to yourself, something rare for a monument of this size and importance.
Like many others in Portugal, Marvão Castle has Moorish origins. When King Afonso Henriques conquered Marvão in the 12th century, the castle was already in place. It’s believed to have been built by the knight Ibn Marwan, who lived there between 876 and 877. Over time, it was expanded and rebuilt — and its incredible hilltop position makes it easy to see why.
São Jorge Castle, Lisbon
São Jorge Castle is one of Lisbon’s most significant monuments and an almost mandatory stop for anyone visiting the Portuguese capital. Located at the top of the city’s highest hill, in the Alfama neighborhood, it also offers some of the best views of Lisbon.
Lisbon is one of the oldest cities in Europe, and its castle has stood there for over 2,000 years. The first fortifications we know of date back to the 1st century BC, having been built, rebuilt, and reinforced several times by different peoples.
The current castle has medieval features, but most of its walls and towers are much more recent, as it was rebuilt during the Estado Novo period after being abandoned for much of the 20th century. Even so, it’s a fascinating place to visit, walk along the ramparts, and enjoy the breathtaking views of the Tagus River and the city.
Sortelha Castle
Sortelha Castle is located in one of the most beautiful and best-preserved medieval villages in Portugal. Walking through its streets and along the walls feels almost like stepping back in time, surrounded by houses and buildings that have changed very little over the centuries. The historic atmosphere, combined with the rocky and unique landscape, makes the visit truly memorable.
Sortelha developed as a strategic town, essential for defending Portugal’s borders over many centuries. The castle, built by King Sancho II, played an indispensable role in protecting the region and was involved in key moments of Portuguese history, including the restoration of independence and the Peninsular Wars.
Today, Sortelha Castle and the surrounding village offer countless points of interest, from the Manueline pillory to the old town hall and historic houses such as the Governor’s House and the House of the Falcons. The combination of walls, towers, and naturally sculpted rocks creates a unique setting where every corner sparks curiosity and fascination, making Sortelha a destination that transports visitors deep into Portugal’s history.
Bragança Castle
Located in the historic center, the imposing Bragança Castle is of great importance to the history of both the city and the country. From the top of its walls, you can see the Montesinho, Nogueira, Sanabria, and Rebordões mountain ranges, offering panoramic views of the city and surrounding landscapes. This elevated and strategic position allowed control of the territory and defense of the region against invasions over the centuries.
Its construction dates back to the 12th century, during the reign of King Sancho I, although it was expanded and reinforced throughout the centuries. In the 16th century, it became one of the seats of the House of Bragança, connecting it to the history of one of Portugal’s most important noble families.
Today, it is considered one of the best-preserved medieval castles in Portugal, allowing visitors to walk along the walls, explore the interior, and feel the medieval atmosphere that marked the region’s history. Inside the impressive keep (Torre de Menagem) is the Military Museum, offering an insight into the local military past.
Tomar Castle
Built in the 12th century by Gualdim Pais, Master of the Order of the Templars, Tomar Castle impresses with its irregular polygonal layout and the architectural ensemble that combines fortress and convent — a rare feature in Portugal. The connection to the Convent of Christ and the Templar cloisters makes the site unique and rich in history.
The castle preserves strong walls, square towers, and semicircular turrets, but what sets it apart is its integration with the city and the convent, forming a harmonious complex that brings together defense, spirituality, and aesthetics. The Keep, the Porta do Sol, and the Porta de Santiago each offer distinct points of interest, with their own stories and details.
Climbing the walls and walking through the courtyards is an experience that transports visitors back to the Middle Ages, with panoramic views over Tomar and the Nabão River. Blending history, architecture, and landscape, Tomar Castle is one of the most fascinating examples of how the Templar military tradition intertwines with Portugal’s history and cultural diversity.
Trancoso Castle
Built on a plateau in Beira Alta, Trancoso Castle is one of the most imposing medieval castles in Portugal. Its strategic location made it possible to control access routes and protect the region from invasions over the centuries.
Constructed in the 10th century during the Christian Reconquest, the castle has an irregular oval layout, crowned by strong walls and five square towers. The keep (Torre de Menagem) stands out for its unique silhouette and its horseshoe-arched doorway — a rare feature among Portuguese castles. The square merlons with pyramid-shaped tops give it a distinct and striking appearance.
