In the heart of the Algarve, perched on a hill on the right bank of the Guadiana River, Castro Marim Castle holds centuries of history and battles. Although human presence in the region dates back to prehistoric times, it was here that Romans and Muslims found a strategically valuable vantage point, taking advantage of its privileged position.
The imposing fortification you can visit today (for a small fee) was built in the 13th century by order of King Dinis, serving as a defensive bastion against invasions and as a watchful sentinel on the border with Spain.
