Guimarães Castle is found in central Alentejo. It is hugely famous because it is well-preserved, in contrast to other Portuguese castles which have been destroyed.

Óbidos Castle 

Óbidos Castle is in the municipality of Oeste. It is a great place for family visits, as the castle is large and perched on a steep hill. This is great for young children because it is more fun than the ancient ruins on other sites, and exerts more energy. 

The castle remains standing despite being conquered many times, the first of which was in the 12th century. Not only has it been modified and reconstructed after disasters, but also been improved and expanded for the public. 

Leiria Castle

Leiria Castle is in the Centro region of Portugal, in the city which it is named after. Like many castles in Portugal, it was built in the 12th century as a defense against invaders. However, it became abandoned several times due to wars, disasters, insufficient funds, and other causes.

Tomar Castle


Tomar Castle is in Medio Tejo, the Centro region of Portugal. It was built under the instruction of Afonso I and cleverly designed to protect the area.

By building the complex on a hill, invaders would inevitably become tired whilst charging toward it. Similarly, the people inside had a clear view of the city, and could easily spot enemy troops. The king also introduced the addition of round towers, because they were increasingly more resistant to obstruction.

Currently, the castle is open to the public and you can identify these protective features!
