To the west of Ilkley, overlooking the Wharfe Valley (England), vandals have used white paint to circle the late Bronze Age design of the Swastika Stone, perhaps the best known prehistoric site in the area. Spiked railings are not enough to protect it, it seems. The pattern of abuse and neglect continues on rock art all over Ilkley Moor. According to the Heritage Action group, action must be taken before these fragile sites are lost forever, like Bradup stone circle that lay just three kilometers southwest of the Twelve Apostles but is now completely gone. Or Weecher stone circle roughly the same distance to the southeast, which was removed at the turn of the 20th century.
