The Puerta de la Justicia (Gate of Justice), a sizable gate that functioned as the primary entry on the south side of the walled complex and was constructed in 1348 during the rule of Yusuf I, is the main gate of the Alhambra. The gate is made of a big horseshoe-shaped archway that leads to a steep ramp that curves into a narrow corridor. On the exterior of this gate, a carving of a hand with five fingers represents the Five Pillars of Islam, while on the interior, a carving of a key represents another symbol of faith in the same location. Later, a sculpture of the Virgin and the Christ Child from the Christian era was placed in another niche right within the gate.
