10 Best Castles to Visit in Portugal

Here are the best castles in Portugal to visit. Did you know that Portugal has over 150 well-preserved structures and over 400 castles, if you include ruins? Today, we will discuss 10 of the best castles to visit in Portugal.

Throughout Portugal’s history, castles have been built all over Portugal. Particularly in the northern, central, and border regions. These castles were mostly built as a defense against the Moors and Spain. You may not be able to visit every single castle in Portugal, but there are so many that you need to visit a few during your vacation.

This is a very family-friendly activity, but you may want to bring a baby carrier (we like the Tula) in addition to a stroller, since castles were not built with strollers in mind!

Do I need a rental car in Portugal? While Portugal has fantastic public transportation, it may be helpful to rent a car, especially if you want to explore and see all of these castles! We recommend AutoEurope for all car rentals!

Castelo de São Jorge (Lisbon)

Located high above Lisbon, Castelo de Sao Jorge offers sweeping views over the city and the Tagus River. The grounds are spacious, making it a good stop for families who want to explore without feeling rushed. It’s easy to pair a visit here with wandering through Alfama or riding one of Lisbon’s iconic trams.

Pena Palace (Sintra)

Pena Palace looks like it came straight out of a fairy tale, with colorful towers and dramatic hilltop views. It’s one of Portugal’s most famous landmarks and a highlight for kids who enjoy castles that feel imaginative rather than formal. Visiting Pena Palace is often a highlight of a Sintra day trip from Lisbon.

Moorish Castle (Sintra)

The Moorish Castle sits along a long stone wall with panoramic views over Sintra and the coastline beyond. Unlike palace interiors, this castle focuses more on walking, exploring, and enjoying the scenery. It’s a good choice for families with older kids who enjoy being outdoors and moving at their own pace.

Óbidos Castle

Óbidos Castle surrounds a beautifully preserved medieval town, making it feel like you’ve stepped back in time. Families can walk along cobblestone streets, browse small shops, and explore the castle walls without needing a long visit. It’s an easy and rewarding stop on a road trip north of Lisbon.

Guimarães Castle

Often called the birthplace of Portugal, Guimaraes Castle is compact and easy to explore. The grounds are manageable for families, and the historical significance adds depth without overwhelming younger visitors. It pairs well with time spent in the charming historic center of Guimarães.

Almourol Castle

Almourol Castle stands on a small island in the Tagus River, which immediately makes it feel special. Reaching the castle by boat adds an element of adventure that kids often love. While the visit itself is short, the unique setting makes it a memorable stop.

Marvão Castle

Marvao Castle sits high above the Alentejo countryside, offering some of the most dramatic views in Portugal. The village and castle feel quiet and uncrowded compared to more popular destinations. This is a great option for families exploring inland Portugal or looking for something a little different.

Monsanto Castle

Monsanto Castle is built among giant granite boulders, making it one of the most unusual castles in Portugal. Kids often enjoy climbing and exploring the rocky landscape as much as the castle itself. The entire village feels unique and unlike anywhere else in the country.

Leiria Castle

Leiria Castle is well-restored and easy to walk through, featuring open courtyards and viewpoints. It’s a good stop for families traveling between Lisbon and Porto who want to break up the drive. The castle feels accessible without being overly crowded.

Silves Castle (Algarve)

Silves Castle is the most well-known castle in the Algarve and stands out for its red stone walls and size. The grounds are open and easy to explore, making it a good cultural stop during a beach-focused trip. It’s a nice way to add variety to an Algarve itinerary without taking up a full day.
