Alhambra's great city wall has four massive gates: Puerta de las Armas, Puerta del Arrabal, Puerta de los Siete Suelos, and Puerta de la Justicia. Two (Siete Suelos and Justicia) were located in the South, and the other two (Armas and Arrabal) in the North perimeter. There is also Puerta del Vino, but unlike the outer four gates that protected the city, it was located inside. One Spanish-Islamic construction feature the gates exhibit, are deflected passageways. Designing their gates in such manner made it easier to defend intruders. On the other hand, inner passageways, like the Wine Gate (Puerta del Vino), serve as entrances and a divider or separator between different areas inside the complex.
