The Alcazaba de Almeria
Click on picture to view at full resolutionMost of the major cities in Andalusia have at least the remains of an Alcazaba or Moorish fortress.  The most famous of the Alcazaba is at the Alhambra.  However Alcazaba de Almeria is more impressive and certainly larger than the one at the Alhambra.  The city of Almeria was probably the most important port and market in Muslim Spain and the fortress was appropriate for such an important city.
