At Obac, there is a dolmen, which the people of the local village call the Llosa (slab) del Corralet. The oldest inhabitants of Biscarbó used to explain that in ancient times there had been a great war and that the slab had marked the place where a king of England had been buried after he had died in combat.
They also explain how two married couples once came to Biscarbó with picks and shovels. They found the dolmen and then set to work digging. They were looking for a treasure that, according to them, had been hidden just below the dolmen. Needless to say, it did not take them very long to give up the task of trying to dig under the dolmen.
