Where did Merlin put the sword in the stone?

In Arthurian legend, Merlin placed the sWord, often referred to as Excalibur, in a stone to serve as a test for the rightful king of England. The sWord was embedded in the stone as a challenge, with the prophecy that only the true heir could pull it out. This act ultimately led to the discovery of Arthur as the legitimate ruler. The stone and the sWord symbolize themes of destiny and rightful leadership.
