fir Gaelic for "manhood stones", originate from Scotland. Manhood stones were used for centuries as tests of strength in Scotland.

There are many examples in Scotland including: the McGlashen Stones the Nicol Stones - The heavier stone weighs 138 kg (304 lbs), and the lighter stone weighs 114 kg (251 lbs) for a total of 252 kg (555.5 lbs) the Inver Stone (121.6 kg (268 pounds)) the Dinnie Stones (two stones weighing 332.49 kg (733 pounds) combined. 188.02 kg (414.51 pounds) and 144.47 kg (318.5 pounds)) the Menzies Stone (115 kg (253.5 pounds)) Both the McGlashen Stones (later known as the Atlas Stones or Castle Stones with relation to the setup) and the Dinnie Stones have been used in numerous Strongman competitions since the 1980s including World's Strongest Man, Europe's Strongest Man and Pure Strength.
