The peninsula Dunnet Head includes the northernmost point of the mainland of which country?

Dunnet Head is a peninsula in Caithness, on the north coast of Scotland. Dunnet Head includes the most northerly point of the mainland of Great Britain. The point, known as Easter Head, is at

58°40′21″N 03°22′31″WCoordinates: 58°40′21″N 03°22′31″W (grid reference ND202767), about 18 km (11 mi) west-northwest of John o' Groats and about 20 km (12 mi) from Duncansby Head. Dunnet Head can be seen also as the western limit of the Pentland Firth on the firth's southern, or Caithness, side (Duncansby Head is the eastern limit). Although Easter Head is the most northerly point on the Scottish mainland, the northernmost point of Scotland lies in the Shetland islands, approximately 170 miles further north.

The headland's boundary with the rest of the Scottish mainland can be defined as a north-south line running from Little Clett (ND220740) to the mouth of Dunnet Burn (ND217709) in Dunnet Bay. This line is followed along most of its route by a single track road, the B855, which links Brough with the village of Dunnet, making this the most northerly road on mainland Britain. From this line, the headland projects westward and northward into the Atlantic Ocean and the Pentland Firth and shelters the more southerly waters of Dunnet Bay.
