Central tower built with sandstone

After we climbed up the stairs, we finally arrived at the top level. Here we were able to enjoy some really great views, because we were now 50 meters from the ground.
The only stone used by Angkorian builders was sandstone, obtained from the Kulen mountains 35 km far away. Since its obtainment was considerably more expensive than that of brick, sandstone only gradually came into use, and at first was used for particular elements such as door frames.
