John o’ Groats lies at the extreme northeastern tip of the mainland of Scotland. John o’ Groats and Land’s End in Cornwall, England, mark the extremities of the island of Great Britain. About 870 miles (1,400 kilometers) of land separate the two places. John o’ Groats is the site of an eight-sided house built by a Dutchman, John de Groot, around 1500. John o’ Groats lies on the shore of the Pentland Firth, which separates the Scottish mainland from the Orkney Islands to the north.
