Angkor, Cambodia ~ 1000s
Ta Keo Temple was built around the early 11th century under the reign of Jayaviravarman (Ta Keo) in Angkor, Cambodia, where many temples are still standing. It is located in a wide plain and natural setting. Sandstone was used as one of the main material, a method which hasn't been introduced largely during the time (Ta Keo).
The are of Ta Keo Temple is enclosed with walls and its main area consists of one main tower in the center with four smaller ones surrounding it. The whole temple, however, was never finished and no one has been able to find the reason of its discontinuation. Whatever the reason was, the temple could have been a great masterpiece if the construction went on. Its walls are not even carved at all, so it just seems like blocks of solid rocks put on top of each other that is shaped into pyramids.
