The main temple complex at Angkor Thom is called the Bayon, which tourists call the smiley face temple for obvious reasons. But the complex itself is much bigger, and has bits and pieces spread out all over the place, including the foundations of the old royal palace, and some government buildings. The foundation photo here is called the Terrace of the Elephants, where the king would view victory processions, and the other photo is of the royal storehouse. There's also a very cool bridge leading here lined with headless Buddhas but Somchai wouldn't photograph it. Angkor Thom also incorporated temples from earlier pre Angkor Wat capitals, most notably Baphuon. This was a huge pile of scaffolding when we were there as apparently the whole thing collapses in a breeze, but I read that it's recently been reopened, and is probably a trip highlight now.
