The taqa is one of the most typical decorative and functional features of the Nasrid Palaces.
It consists of a normally small niche carved out of a wall, which was used for storing water vessels. The water was either for drinking or for washing hands. The taqas were designed as part of and in proportion with the decorative project for the space as a whole, and above all for the walls into which they were inserted.
Taqa is an Arabic word meaning niche, cupboard or opening in a wall, although in the Oriental Islamic world 'taq' means arch or arcade built with wooden support structures.
