The Moorish Castle

Sintra, Portugal, Portugal

---

The Moorish Castle, or Castelo dos Mouros, in Sintra, Portugal, is a rugged 8th-9th century fortress built by Muslim rulers on a hilltop peak amid dense forests, designed to defend the region and monitor sea routes to Lisbon.

It features dramatic winding walls following the rocky contours, towers like the Tower of Homage, cisterns, and silos for grain storage, offering sweeping panoramic views over Sintra, the Atlantic Ocean, and distant Lisbon.

Conquered by Portugal's first king, Afonso Henriques, in 1147 during the Reconquista, it later passed to the Knights Templar, underwent medieval expansions under kings like Sancho I and Ferdinand I, fell into partial ruin after the 1755 earthquake, and was romantically restored in the 19th century by King Ferdinand II as part of Sintra's Romanticist revival.

Today, it's a UNESCO World Heritage site popular with visitors for its atmospheric ruins, steep hikes, and evocative history blending Islamic and Christian legacies.
