Alcazaba of Granada. Alhambra. Andalusia.
An alcazaba (Spanish: [alkaˈθaβa], Galician: [alkaˈθaβa]), alcáçova (Portuguese: [ɐɫˈkasuvɐ]) or alcassaba (Catalan: [əɫkəˈsaβə]) is a Moorish fortification in Spain and Portugal. The word derives from the Arabic word القصبة (al-qasbah), a walled-fortification in a city.
Alcazabas are present in Almería (the largest), Antequera, Badajoz, Granada, Guadix, Málaga, Mérida (the oldest), Molina de Aragón and Alcalá la Real. The alcazaba in Granada constitutes the oldest portion of the Alhambra palace.
The word alcazaba should not be confused with alcázar (Spanish) and alcácer (Portuguese), which have their etymology in the Arabic al-qasr, which in turn derives from the Latin 'castrum', and denotes a fort or castle.
