Wikipedia shows Ta Prohm as being built as one of the early Mahayana Buddhist temples by an early Buddhist king, Jayavarman VII. His immediate predecessors were Hindu, except for one earlier Buddhist king. It says this one was built in honor of his mother, and another in honor of his father.
I usually get the impression however that the Buddhism/Hinduism split is not as big as it seems, since sometimes the Hindu gods seem to have converted to Buddhism and became Buddhist saints.

Whoops. Thank you. I added a comment about a transition of Ta Prohm just now. ^^;
I remember Preah Khan -one of the famous temples near Angkor Wat- was a Mahayana temple.
But I had forgotten Ta Prohm was also a Mahayana temple at first as Preak Khan. It was changed to a Hindu temple (probably after a death of Jayavarman VII). He is a rare king among the then Khmer kings because he made much account of Mahayana Buddhism more than Hindu. 
I know there are some Mahayana temple remains near Angkor Wat. If you are interesting in temple remains, Preah Khan is just very interesting historical records. There are a lot of caved relieves of Buddhist saints. But all of them were cut their face... You can look a religious opposition and a power struggle in ancient times. :)
