The Victory Gate is an entrance and exit on the east side of Angkor Thom. I passed through near the end of the trip when I wanted to visit a few sites a second time. The photos were taken around 8:00am. I was lucky no one was around. Most enter Angkor Thom from the south and spend the morning at Bayon. It is worth the effort to take a different route into Angkor Thom so you enter 
through the Victory Gate early in the morning. This is easy if you hire a Tuk Tuk. A tour operator may have their own agenda that they will not deviate from.
