The Tribute Tower

The Tower of Homage is one of the highest -26 m - and is also a tower dedicated to housing. It has a total of six plants, and it is believed that it established the founder of the Alhambra, AL-HAMAR, when it decided to build his palace here.

This was the original entrance to the Citadel. It's next to the Tower-Cube to the right.
At its low, there is a dungeon that was also used as a warehouse for grain, salt and spices. http://www.alhambra.org/eng/index.asp?secc=/alhambra/alhambras_guide/the_alcazaba/the_tribute_tower
