A popular story connects St. Agnes with the giant Bolster. This relates how, in order to rid herself of his persistent wooing and the countryside of his tyranny, she (St. Agnes)challenged him to fill a small hole in the rocks at Chapel Porth with his blood as a token of his love. To this the giant agreed, not knowing that the hole emptied into the sea, with the natural consequence that he bled to death!
The hole at Chapel Porth still retains the evidence of the truth of this tradition in the red stain which marks the track down which flowed the giant’s blood!
