I spent one day in Siem Reap, Cambodia touring the various temples. The first temple I visited, Angkor Wat, took hours to tour, and I still didn't see the whole thing.. It is the the largest religious structure in the world. The walls are covered in stone carvings depicting ancient religious stories. Angkor Wat is a strange combination of Buddhist and Hindu symbolism, having been used by both religions at different points in history. Aside from being really ancient and beautiful, I met some cute little local boys there. I gave them stickers, and they taught me to use their whirly toy.
Some makeshift temples with offerings.
