The Black Stone of Mecca is a religious artifact of the Muslim faith. According to tradition, it dates back to Adam and Eve. Today, the stone is the eastern cornerstone of the Kaaba, a stone building of great antiquity towards which Muslims direct their prayers. It measures approximately one foot in diameter, standing over four feet tall.
Pilgrims walk in circles around the Kaaba, stopping to kiss the Black Stone on each of their seven laps. If they are unable to kiss it, they instead point to it.
During the Middle Ages, the Stone was broken into many pieces, and is not help together by a silver frame, attached using silver nails.
