The word Cromlech is generally used among French, Portuguese and Spanish to define stone circles. In English, it refers to prehistoric megalithic tombs. Typically, it has a mound encircled by large upright stone and a capstone. These stones are the remains of ancient stone chamber tombs. All complex examples of megalithic architecture are generally termed as cromlech. These architectures are found only in British Isles and were set as a part of religious rites. The last cromlech is called Stonehenge, in Southern England.
