Portugal is a land of kings, knights, and explorers—a country where medieval castles still crown hillsides, overlooking whitewashed villages, vineyards, and winding rivers. These fortresses are more than just stone walls; they are living reminders of Portugal’s turbulent past, from battles with Moors and Castilians to centuries of royal power.

Each castle has its own story to tell. Some are soaring strongholds built to defend the nation’s borders, others romantic ruins where history lingers in every arch and tower. Exploring them allows travelers to step back in time, imagining medieval sieges, royal processions, and watchful sentries scanning the horizon for invaders.

Portugal Magik Private Tours often incorporates castle visits into private itineraries, especially for guests who appreciate both history and dramatic landscapes. Traveling in a private Mercedes-Benz vehicle, accompanied by an English-speaking driver-guide, allows you to reach these sites with ease—often combining them with nearby villages, vineyards, or UNESCO heritage cities.

Here are seven medieval castles in Portugal that should be at the top of your list.

1. Castle of Óbidos (Castelo de Óbidos)

Perched above one of Portugal’s most charming villages, the Castle of Óbidos is a picture-perfect medieval fortress. Its origins date back to Roman times, but it gained prominence after the Christian reconquest in the 12th century. For centuries, it was gifted to Portuguese queens as part of their dowry, earning Óbidos the nickname “the Town of Queens.”

The entire village is encircled by medieval walls, and walking along the battlements offers sweeping views of red-tiled rooftops and the surrounding countryside. Today, part of the castle has been transformed into a Pousada (historic inn), allowing travelers to sleep within its ancient walls.

2. Castle of Guimarães (Castelo de Guimarães)

Known as the “Cradle of Portugal,” the Castle of Guimarães is where the country’s first king, Afonso Henriques, was born in the 12th century. This imposing granite fortress, with its tall keep and defensive towers, symbolizes the very birth of the Portuguese nation.

Walking through its grounds, visitors can imagine the battles that secured Portugal’s independence. The nearby Palace of the Dukes of Braganza adds to the medieval atmosphere, making Guimarães a must-visit for history enthusiasts.

3. Castle of Tomar (Castelo de Tomar)

Few castles in Portugal are as closely tied to legend as the Castle of Tomar, founded in 1160 by the Knights Templar. This fortress became the headquarters of the order in Portugal and later the stronghold of the Order of Christ, which played a central role in the Age of Discoveries.

Its highlight is the Charola, a circular Templar church inspired by the Holy Sepulchre in Jerusalem, adorned with extraordinary frescoes. Together with the Convent of Christ, this UNESCO World Heritage Site is one of Portugal’s most extraordinary medieval monuments.

4. Castle of Marvão (Castelo de Marvão)

Rising dramatically from a granite outcrop in the Alentejo region, the Castle of Marvão is one of Portugal’s most breathtaking strongholds. Built during the 9th century and later reinforced by King Dinis, it overlooks vast plains that stretch into Spain.

The climb to its ramparts rewards visitors with panoramic views of rolling hills, olive groves, and distant mountain ranges. The surrounding village of Marvão, with its narrow cobbled streets and whitewashed houses, is equally enchanting—a true time capsule of medieval Portugal.

5. Castle of Almourol (Castelo de Almourol)

Standing on a small island in the middle of the Tagus River, the Castle of Almourol is one of the most romantic castles in Europe. Originally of Moorish origin, it was conquered in 1129 and entrusted to the Knights Templar.

Reaching the castle requires a short boat ride across the river, heightening the sense of mystery. Its towers and battlements rise dramatically from the water, making it a favorite for photographers and history lovers alike. At sunset, the castle glows golden, casting a reflection across the river’s surface.

6. Castle of Monsaraz (Castelo de Monsaraz)

In the heart of the Alentejo, the Castle of Monsaraz guards a hilltop village that overlooks the vast Alqueva reservoir. Dating back to the 13th century, the fortress once served as a key defensive outpost along the Spanish border.

Today, the castle’s courtyard doubles as a rustic bullring, and its ramparts offer some of the most spectacular views in Portugal. The village itself is a delight, filled with stone-paved streets, artisan shops, and traditional taverns serving regional wines.

7. Castle of Silves (Castelo de Silves)

The Castle of Silves, located in the Algarve, is one of the best-preserved Moorish fortresses in Portugal. Built with striking red sandstone, it dominates the town of Silves, once a flourishing Moorish capital.

Inside, visitors can explore reconstructed towers, walk along the mighty walls, and admire the sweeping views over orange groves and the Arade River valley. The castle’s history reflects the region’s long struggle between Moorish and Christian forces, making it a fascinating site for cultural exploration.
