What different types of gate are there in the Alhambra?

There are two main types of gates in the Alhambra: exterior ones for defence such as the Puerta de la Justicia on the outside walls of the fortresses and interior ones to control access to different parts of the complex. As exterior gates provided points of weaknesses, they were built with right angles inside. The interior gates, meanwhile, like the Puerta del Vino, were built with benches inside on either side for the guards.
