I'm trying to figure out what this temple is called and where it's located. Does anyone know?
Looks like Wat Chaiwatthanaram in Ayutthaya, Thailand, north of Bangkok:

While the tubular central Khmer-style prang does indeed look a bit like Angkor Wat, the red brick is distinctively different and the tilted chedi dome (right in the original, far left in the photo above) and the brick terraces all around are giveaways.
And for once, this answer was not derived through Google image search, but actually having visited: Ayutthaya's temples have quite a distinctive look!
