Fingal’s Limpet Hammers

I couldn’t resist the name of these standing stones. At a leaning 10ft and 8 1/2 ft they stand 45 feet apart. Apparently a limpet hammer is a stone tool used for persuading the poor molluscs off their rocks, a term also applied to any number of mysterious stone tools by bemused archaeologists (none of whom had probably ever eaten a limpet).
