Built by Jayavarman VII in the late 12th- early 13th centuries. The stone carved faces on the towers represent the bodhisattva Avalokitesvara, but also resemble the founder.
The tube house gets its name from its characteristic dimensions. With a narrow face on the street (often as narrow as 2 meters) and a long space on the inside (they can be up to 80 meters deep) these houses do indeed resemble tubes. This style dates back to the Le Dynasty (1428-1788), when they were popular as a way to fit as many stores on a street as possible. Typically, the houses had a shop area in the front and used the back areas for relaxing and sleeping.
