Caithness is known for its stone rows; foremost amongst these is unquestionably the Hill O' Many Stanes at Mid Clyth. The stones themselves are extremely unremarkable as standing stones go - the tallest amongst them is less than a metre tall. What sets this apart from all other Scottish stone rows is the fact that there are over 200 stones standing out of what may have originally been around 600.

The stones are laid out in twenty-two almost parallel rows running down a hillside, although the rows actually fan out a little from top to bottom.

It has been suggested that the stones formed a lunar observatory as major and minor standstill points of moonrise and moonset can be sighted using various alignments of the stones. Which doesn't even begin to explain why so many stones were used here.
