Cascais Citadel
Highlight • Castle
Here is a summary of what makes it special:
1. Living History
The Citadel is not just a ruin; it is a restored fortification with three main parts:
The Fortress of Nossa Senhora da Luz: Built between the 15th and 17th centuries to defend the coast from pirates and Spanish troops.
The Royal Palace: It became the summer residence of the Portuguese Royal Family in the late 19th century (King D. Luís I). Because of this, Cascais transformed from a fishing village into a "Court town," attracting the aristocracy.
Presidential Residence: Today, the Palace is still an official summer residence for the President of Portugal, but parts of it can be visited (guided tours are often available via the Museum of the Presidency).
2. The "Art District" (Modern Twist)
A few years ago, the Citadel was revitalized. It now houses a luxury hotel (Pestana Cidadela) and the Cidadela Art District.
Open Courtyards: You can walk freely into the fortress courtyards. It is no longer a closed military zone.
Galleries & Studios: The old barracks have been converted into art galleries, studios, and bookshops. It is very common to see artists working there.
"Déjà Lu" Bookshop: A charming charity bookshop located inside the complex, highly recommended for book lovers.
3. What to Do
Walk Through: It serves as a perfect connection between the Marina and the Culture Centre/Marechal Carmona Park.
See the Views: The walls offer great angles for photos of the marina and the sea.
Cultural Stop: Visit the Palace museum or simply wander the Art District to see contemporary sculptures contrasting with ancient stone walls.
Summary: It is a place where you can see 16th-century cannons and 21st-century modern art in the same 10-minute walk.

5th of October Square, Cascais Town Hall and Statue of Dom Pedro I
Highlight • Monument
Cascais has a rich history dating back to the Lower Paleolithic.
In the 14th century, it was a fishing and farming village dependent on Sintra.
On June 7, 1364, the inhabitants of Cascais petitioned King Pedro I to elevate the village to the status of a town, which was granted. This marked the beginning of its administrative and judicial autonomy.
