The pillars are carved from the natural limestone layers of the hill's bedrock. Limestone is soft enough to work with the flint or even wood tools available at the time, given practice and patience.Sandstone is formed from layers of sandy sediment that is compacted and lithified. Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves. For instance, most limestone forms at the bottom of the ocean from the precipitation of calcium carbonate and the remains of marine animals with shells.
