Saint Sebastian Fortress, Military fortress in Castro Marim, Portugal.
The fortress presents five massive bastions constructed on Revellin Hill, featuring thick defensive walls and strategic positioning overlooking the surrounding territory.
Constructed during the 17th century, this fortification formed an essential component of the defense network protecting the Algarve region from maritime invasions.
The structure exemplifies Portuguese military engineering techniques through its irregular layout, which adapts to the natural terrain while maintaining defensive capabilities.
While the interior remains closed to visitors, the external architecture and defensive elements can be observed from multiple vantage points around Castro Marim.
The fortress connects directly to Castro Marim's medieval castle through its northern entrance, creating an integrated defense system across different historical periods.
