Formed by a sedimentary rock called marl, its crisp white color is whiter even than the two sand beaches which embrace its east and west boundaries. The constant action of waves, wind and weathering over the course of millennium have carved the shape of steps into the cliff, creating a sun worshipers' magnet during the hot summer months. The natural landmark drew invasions from the Moors from northern Africa, the Saracens and Turkish pirates, thus the name.
Most of the time the Scala appears to be a snow white, slanted layer cake, while at other times of the day the color of the cliffs can change dramatically from pink to orange to yellow and even blue. Unlike the White Cliffs of Dover in England (made of chalk), the Scala's geology is made of a sedimentary limestone and clay. Its stairs are soft and rounded and very precarious, but are still visited by many people who climb and sun themselves on the Scala.
