The Alhambra

The Alhambra is a fortified palace complex in Granada, Spain, renowned as a landmark of Islamic architecture and the sole surviving medieval Islamic palace in good condition. It also features significant Spanish Renaissance architecture. Construction began in 1238 under Muhammad I Ibn al-Ahmar, the first Nasrid emir and founder of the Emirate of Granada, the last Muslim state in al-Andalus. The complex was built on Sabika hill, a spur of the Sierra Nevada that previously held older fortresses and the 11th-century palace of Samuel ibn Naghrillah. Later Nasrid rulers made continuous modifications, with the most defining additions to the royal palaces occurring in the 14th century under Yusuf I and Muhammad V. After the Christian Reconquista ended in 1492, the site became the royal court of Ferdinand and Isabella—where Christopher Columbus received royal backing for his voyage—and the palaces were partly altered. In 1526, Charles V ordered a new Renaissance-style palace built directly next to the Nasrid palaces. Over subsequent centuries, the Alhambra fell into decay, with squatters occupying its buildings. Napoleon’s troops destroyed parts of it in 1812. Afterward, it attracted British, American, and other European Romantic travelers, most influentially Washington Irving, whose *Tales of the Alhambra* (1832) drew global attention. It was among the first Islamic monuments to undergo modern scientific study and has seen numerous restorations since the 19th century. Today, it is a major Spanish tourist attraction and a UNESCO World Heritage Site.

During the Nasrid period, the Alhambra functioned as a self-contained city, separate from Granada below. It included amenities typical of a Muslim city: a Friday mosque, hammams (public baths), roads, houses, artisan workshops, a tannery, and a sophisticated water supply system. As a royal city and citadel, it housed at least six major palaces, mostly along the northern edge with views over the Albaicín quarter. The best-preserved and most famous are the Mexuar, the Comares Palace, the Palace of the Lions, and the Partal Palace, which are the main attractions today. Other palaces are known from historical records and modern excavations. At the western tip lies the Alcazaba fortress. Numerous smaller towers and fortified gates line the walls. East of the Alhambra, outside its walls, is the Generalife, a former Nasrid country estate and summer palace with historic orchards and modern landscaped gardens.

The Nasrid palaces’ architecture follows the Moorish tradition developed over earlier centuries. It centers on the courtyard as a core space and organizing unit for surrounding halls and rooms. Courtyards typically feature water elements at their center, like a reflective pool or fountain. Decoration is concentrated on interiors, using tile mosaics on lower walls and carved stucco on upper walls. Geometric patterns, vegetal motifs, and Arabic inscriptions are the main decorative themes. Muqarnas, a stalactite-like sculpting technique, is used for three-dimensional features such as vaulted ceilings.

The name Alhambra comes from the Arabic *al-Ḥamrā’*, meaning “the red,” with the full form being *Qal‘at al-Ḥamrā’* (“the red fortress”). The Arabic definite article “Al-” is typically ignored in English and Spanish usage, where the name is given a definite article. The “red” refers to the reddish color of its walls, built from rammed earth; the color comes from iron oxide in the local clay. Most current names for specific structures within the Alhambra were imaginative labels coined after the medieval period, often in the 19th century. The original Arabic names of Nasrid-era buildings are unknown, though some scholars have linked certain buildings to names in historical sources.

Evidence of a Roman presence is unclear, but archaeologists have found ancient foundations on Sabika hill. A fortress or citadel, likely from the Visigothic period, existed there in the 9th century. The first mention of *Qal‘at al-Ḥamra* occurred during battles between Arabs and Muladies under ‘Abdallah ibn Muhammad (r. 888–912). Contemporary documents describe the red castle as quite small, with walls unable to repel a determined army. The first reference to *al-Ḥamrā’* appears in poetry attached to an arrow shot over the ramparts, recorded by Ibn Hayyan (d. 1076). In the early 11th century, the Granada region was dominated by the Zirids, a Sanhaja Berber dynasty.
