Three temples are replicated in this sculptor's garden. Angkor Wat, Bayon, and Bantay Srei. It's not really what one can call a museum, it's just these three sculptures in a garden! It's nice to see the whole picture and the above view but the sculptures are not very well maintained and not always really precise. Anyway you'd have a hard time staying more than 10 minutes there (for $1,5 entry fee). If you're in that part of town it might be nice but if you can't go there to see them you're really not missing on anything spectacular!
