The Stair of the Turks, also known as the "Scala dei Turchi," is a unique and beautiful natural formation located on the southern coast of Sicily, in Italy. It is a large, white, cliff-like structure made of marl, a type of sedimentary rock that is composed of clay, silt, and other minerals.

The Stair of the Turks is known for its striking, white appearance, which is created by the presence of calcium carbonate deposits in the marl rock. The cliff-like formation rises dramatically from the sea, and is one of the most distinctive and recognizable landmarks along the southern coast of Sicily.

One of the main attractions of the Stair of the Turks is its accessibility. Visitors can easily climb the steps to the top of the cliff, where they can enjoy panoramic views of the surrounding coastline and sea. The formation is also a popular destination for hiking, swimming, and sunbathing, and is considered one of the most beautiful and serene spots in the region.
