The south gate with 3 faced towers.
Sightseeing in Siem Reap/Angkor picture - The central tower has faces facing each of the four cardinal directions. The Angkor Thom Gates, particularly the south gate, are good examples of the Jayavarman head, a motif that is seen throughout this temple area. Note the partial ruins of the god Indra sitting atop a three-headed elephant statue (one of four) gathering lotus flowers. This gate was restored between 1944 & 1946.
