Castillo de Alhambra

Spain, Spain

---

The Alhambra in Granada, Spain, is a majestic 13th-century fortress-palace complex built by the Nasrid dynasty atop the Sabika hill, blending military strength with exquisite Islamic architecture featuring intricate arabesques, horseshoe arches, and serene courtyards like the Patio de los Leones.

Founded by Muhammad I in 1238 as a red-walled citadel (qa'lat al-Hamra), it reached its zenith under Yusuf I and Muhammad V in the 14th century with opulent palaces, the Alcazaba barracks, and the Generalife gardens, symbolizing Granada's final Muslim stronghold.

Conquered by the Catholic Monarchs in 1492, it became a royal residence with Renaissance additions like Charles V's Palace, later serving as a fortress and barracks before restoration as a UNESCO World Heritage site.
